XEN Modification Guide - Synergies and Percentage values!
By Valkerion™
A detailed guide of actual XEN values shown in percentile, with other synergies and combos explained.
For everyone wondering what on earth "slightly increases damage" means, look no further.

WIP. I am still working my way to acquiring all XEN, feel free to let me know what XEN I have to look out for and I will add them to the list.

What does "moderately increases damage" even mean?
This guide is WIP, and based on thorough testing in the shooting range comparing single XEN at a time for concrete % values, and then testing some in combinations with others or multiples of the same copy for further details. I will test all values myself before adding to the guide but please let me know about any synergies you have found or other XEN I should look out for to add to the list. Dedicated to all those who have often wondered; "what the hell does slightly, significantly, or moderately even mean?".

...The short answer is, they mean nothing and there is little to no correlation between what the devs wrote in the English descriptions and what the modules truly do, so I decided it was worth finding out myself.

🔹Categories marked with a blue diamond are related to XEN Boosters (Insert buffs)
🔸Categories marked with an orange diamond are related to XEN Morphs. (Skill changes)

Enjoy!


Terminology Guide and Information
https://steamuserimages-a.akamaihd.net/ugc/5841806006839924834/C0891295D7E110984242D9A2454A5614B56BB0FF/?imw=256&&ima=fit&impolicy=Letterbox&imcolor=%23000000&letterbox=false
Base Damage Increase / Damage Boost:
These effects multiply off the base damage, additively.
Ex. 100 Damage with four Strong IV (+25% each) is 200 damage.
Damage Multiplier:
These effects multiply off each other generally, after the above increases, and after each other.
Ex. The above 200 damage with CQC I (+18% Mult) is 236 damage. A second CQC I becomes 278.48 (236*1.18).
Increased Firing Rate:
Decreased cooldown.
Multiple firing rate increases generally work the same as base damage increases (additive), and do not multiply off each other.
Ex. +10% Firing Rate turns 10 second cooldown to 9 seconds. Another lowers it to 8 seconds. Chain (-70%) with 3 Trigger Finger I (+10% each) applies -40% to the base cooldown. (1->1.4)
XEN Morph:
A weapon 'type' for the Core Gun such as Heavy, Light, Grenade.
XEN Booster:
Mods for Core Guns that change how a XEN Morph performs.
Booster Order:
Booster order does not matter. All XEN Boosters are calculated a predetermined way regardless of insertion order.
Damage Boosts: Strong, Condensed.
Damage Reductions: Purify.
Damage Multipliers: Multiply, CQC.
{Base Hit Damage + [(Base)*(Damage Boosts % A+B+C)] - [(Base)*(Damage Reductions % A+B+C)]} * (1+Damage Multiplier A) * (1+Damage Multiplier B) * (1+Damage Multiplier C) --

Barrel / Gear
Actual Observed Effect
In-Game Description
Turbine Barrel
Turbine barrel gives +100% damage on the shot fired after a charge, taking about 5 seconds to power up. Regular shots have no bonus. No cost or fire rate changes. Inexplicably, this barrel gives about a 500% damage boost to the Chain morph. No longer gives 500% extra damage to Chain Morph, only 100%.
The barrel comes with a self-recharging turbine, which when charged boosts its damage.
Heavy Barrel
Heavy barrel gives ~50% damage increase, but 50% firing rate decrease (1.5x cd)
Increases firing interval and greatly increases the damage dealt.
Double Tap Barrel
Double tap causes you to do 2* ~60% damage shots. The second shot has a short delay after the first, affecting fire rate and doubling recoil. It also reduces the hits and duration of many non-bullet based morphs on top of the damage reduction, vastly hurting your damage potential.
Two bullets can be fired in quick succession but each bullet deals less damage.
Scatter Barrel
Scatter barrel causes you to do 3* ~40% damage shots simultaneously. The second and third bullets are offset in a cone from center aim. The spread is much tighter if you aim down sights. It also reduces the hits and duration of many non-bullet based morphs on top of the damage reduction, vastly hurting your damage potential.
Enables three-shot burst but each bullet deals less damage.
Regular Barrel
A mass-produced gun barrel that slightly increases your hip-fire accuracy.
Airborne Helmet
Bonus, the helm ticks the cooldown reduction repeatedly while remaining airborne, 1s removed from CDs every second in the air, effectively doubling cooldown rate. A great helm for skill cooldowns. Gives a stacking buff for being airborne to player's base attack value. (Downside, only gives up to 5 stacks of the buff, not 10.)
Speed up the cooldown recovery of all skills after staying airborne for 1 second. For every 1 seconds(Epic and below) / 0.5 seconds(Legendary) airborne thereafter, gain one stack of [Aerial Combat].
Support Core Gun
Slightly bugged, ALL Morphs show a reduced cooldown, but when actually used, only the ones over 8s are reduced. 1:Spray 2:Cooldown Field 3:Healing Range
A Core Gun fitted with a cooldown device that reduces the Firing Interval of all XENs with an interval of over 8s by 25%.
Rapid Core Gun
Every shot fired without reloading adds a stack of fire rate increase, up to 60 stacks. (Legendary) The fire rate increase is extremely powerful for Morphs like Inferno paired with Free Fire, since fire rate bonuses are additive, resulting in approaching 0 delay on refire. Shot multiplication with barrels multiplies the stacks gained per shot.
A Core Gun fitted with a XEN accelerator for increased rate of fire.
Command Core Gun
1:Spray 2:Focus 3:Load 4:Healing Range?
A Core Gun favored by Commanders. Press R while in Command Mode to toggle Infrared View.
Explosive Core Gun
1:? 2:Explosive Arrow? 3:Chain Reaction
A Core Gun fitted with an area booster chip that boosts the effective range of area-type XENs by 30%.
Drum Mag Core Gun
1:Inferno 2:Scatter Grenade
A Core Gun with a 120-round drum mag.
Marksman Core Gun
There is a hidden bonus of about 0.95% (slightly under 1%) dmg per 10m distance from target. The cap is 50% (reached from extreme height stacking with missile) Comes with Sniper-focused Morphs. 1:Heavy 2:Pinpoint Explosion
A heavy Sniper Core Gun favored by sharpshooters.
Cavalry Core Gun
Unfortunately, not only was there no noticable reload speed increase, but a recent patch allowed players to reload while sprinting regardless of this being the feature of this gun. Rather pointless now. Still comes with useful Morphs you can remove. 1:Scatter Shot 2:Elemental Ball 3:Adrenaline (Either)
A Core Gun fitted with a quick-load mag for fast reloads. Enables reloading while sprinting.
Approx damage per Attack point
(Firing Range)
0.2313624679
  • "Approx damage per Attack point": versus static firing range enemies, a flat amount of damage was added per attack point, shown above. This will vary against enemies with different defenses, but was worth mentioning.
  • In regards to the dmg-atk ratio, higher damage ratios were observed at higher total atk values, cause undetermined.

XEN
Actual Observed Effect
In-Game Description
Epic
Chain
70% cost increase. 70% firing rate decrease. +1 Hits with all the effects of the first hit. Only a pure DPS increase of 17.6%. Hits the same spot, so both will hit weakpoints, but they have independent crit chance. Added hits trigger the same hp threshold for Mighty Strike, as ex.
Trigger an extra Morph XEN when hit.
Epic
Advanced
A XEN with different effects for different Morphs. Generally increases duration based Morphs by 20%, stacking. Hits +1: Pinpoint Strike, Scatter Grenade. Hits/Dur +20%: Gravity. Chain (Morph) hits increased by 8(1), 17(2) 23(3). No change for 4 or more on Chain. Increases ammo loaded by Load Morph.
Increases XEN efficiency.

Uncommon
Entangled State
Self explanatory but has interesting synergy with additional light strikes. Each light strike added will hit the initial target plus the additional two targets (2+1 hits added per light strike) and the standard damage increase for multiple light strikes applies to them as well. (+15% Multiplicative damage to all Light Strikes). Additionally, 50% increased firing cost.
Hitting an enemy applies [Light Strike] to 2 other nearby enemies.
Epic
Elemental Entangle
Same as with Entangled State, but doesn't increase the cost as well as adding elemental build-up, making this a very strong ability.
Hitting an enemy applies [Light Strike] and [Elemental Build-up] to 2 other nearby enemies.
Synergy
ES/EE + 1*LS
Adding 1 Light strike adds ~53.43% more dmg. (total ~117.93% over base)

Adding 4 Light strikes adds ~271.24% more dmg. (total ~427.32% over base)
Epic
2*Elemental Entangle
The two other targets both take two light strikes. With each light strike, two hits will be added to the additional two targets. (4+1 hits added per light strike)
Hitting an enemy applies [Light Strike] and [Elemental Build-up] to 2 other nearby enemies.

Uncommon
Torment I
Piercing damage is 1% of the enemy's *remaining* HP, making it weaker as you weaken the enemy.
Hitting an enemy's weakness triggers 2 [Piercing]. - Deals damage equal to 1% of the enemy's Max HP.
Epic
Torment II
Functions as stated.
Hitting an enemy's weakness triggers 4 [Piercing]. - Deals damage equal to 1% of the enemy's Max HP.
Rare
Apex Predator I
Functions as stated.
Damaging enemies with more than 80% HP remaining applies [Piercing] 4 times.
Epic
Apex Predator II
Functions as stated.
Damaging enemies with more than 80% HP remaining applies [Piercing] 6 times.
Synergy
Piercing Synergy
Piercing effects trigger off every hit bullet, so it is very easy to maximize these for example with the scatter morph and scatter barrel, quickly reducing any enemy to very low HP. Can be great to chunk high health enemies down, but won't be very effective after the first hit if using apex predator, but with torment is very powerful, provided the enemy has a weakness easy to hit. (Or at all, like beacons.)
Uncommon
Pinprick
15% dmg increase to Light Strikes. No noticable effect when used with torment. You get the same dmg increase from multiple Light Strike XEN, but no increased amount of hits, making this worthless unless you lack Light Strikes early on.
Increases the damage of [Light Strike] and [Piercing].
Uncommon
Unstable I
Variance in damage appears to be from -15% to +30-35%, with something like 10% chance of dealing exactly double damage (separate from a crit). Needs testing if it is a damage increase or multiplier.
Damage and efficiency fluctuate randomly and slightly.
Light Strike 5-7 "*Hyp" for Hypothetical, using already determined math.

XEN
Observed Effects and Synergies
C-B
Regular
Standard bullet. Reduced to 80% dmg over ~35m. Further to 55% over ~60m.
This is what I used for baseline dmg comparisons to all other Morph XEN.
R-A
Pinpoint Explosion
Fires a pinpoint accurate marker that causes four strikes to the initial location from above every 1.5s. Number of strikes is lowered by scatter barrel to two. Advanced XEN increases number of strikes by 1 and duration by 1.5s each.
R-E
Suppression Field
Slows enemies in an area for roughly ten seconds. No damage. Ticks 13 times for bonus hits (Light Strike). No visual duration increase, Advanced XEN may work the same here as healing range. (+20% duration each but no visual change)
H-E
Radiance
25% increased damage to affected targets. Either it isn't really reducing armor or the way armor is calculated is simply the opposite of damage calcs. Advanced XEN increases duration by 20% each.
U-B
Spray
Fast firing bullets. -46% dmg. More bullet drop than regular, curves around 40m. Three damage ranges. Damage falloff: 35m:80%, 50m:55%.
E-A
Splitter
Fires an orb that travels 5m, then bursts into a semicircle fan of five bullets that home in on enemies. The orb stops on contact with an enemy and still bursts. The orb deals no damage. The five bullets deal 35-45% randomly increased damage. No damage falloff and seeks targets at long range.
R-A
Scatter Grenade
Scatters six landmines from point of contact that last roughly 26 seconds. They only detonate on enemy contact. 1 more mine released per Advanced XEN. With scatter barrel, 3 Adv: +3 Mines, 5 Adv: +6 Mines.
H-A
Gravity
Creates a gravity well at location that hits (pulls) twelve times for 6 seconds, then explodes. No damage on the pull hits unless you use Light Strike or other hit adding XEN. Initial bullet fired is pinpoint accurate. Advanced XEN add duration and pulls.
E-B
Inferno
The rate of fire decrease seems to be flat, if you slow down your ROF the top speed will not be good, but if you increase it, the benefits are extreme (approaching 0 firing rate). Pairs greatly with Free Fire and Rapid Core Guns. Additionally, no bullet drop or damage falloff, comparable to heavy rounds.
R-B
Light
Performs as an SMG. -62% dmg. Slightly worse bullet drop to spray, significant damage falloff (three ranges). Damage falloff: 20m:85%, 30m:55%.
R-A
Slingshot
Deploys a single-use launch pad at location. Last about 12.5 seconds. If hitting an enemy immediately applies the jump effect to the enemy. Supposedly applies two stacks of [Vulnerability] (-10% damage resistance) to enemies until they land. Has no effect on damage, unknown if the ability functions or if firing range enemies have 0 resistance. Initial bullet fired is pinpoint accurate. Advanced XEN increases duration by 20% each.
L-B
Scatter Shot
Essentially a shotgun, firing 8 rounds for -51% dmg each. Damage drops over 10m distance down to 33% before bullets disappear around ~20m. Damage falloff: 10m:80%, 15m:45%, 20m:33%.
L-A
Missile
Fires a missile with some curve starting around 40m. AOE of about 6m. 875% damage boost on direct hits down to ~387% at the edge of the AOE. Strongly pushes the player back, with a scatter barrel can launch yourself extremely high into the air. Light Strikes only apply to direct hits.
L-A
Energy Arc
Shoots two floating tethered orbs with energy arcing between them, hits everything it passes through for the same damage. Speed and range is based on speed player is moving when fired. Reaches 10m when not moving. Reached up to 65m with sprint+crouch @520 movespeed (+120 boots). [Pure] says it does not deal weakness damage. This seems to also cause crit bonus to become 0 (but shows crits).
L-B
Slasher Round
Fires a round similar to heavy with -36% power that triggers three additional damage procs shortly after with 90% increased power each. All four hits proc light strikes at scaled dmg. No falloff.

Rarity
XEN
Observed Effects and Synergies
U-A
Divine Might
Fires an extreme velocity round that deals random "additional" damage for one total hit. Can crit on top of dealt dmg. The Light Strike dmg is always the same so the base dmg appears to be -37%. The bonus damage appears to be from ~2% to ~96% of your attack power (record dmg in 123 attempts), with an average power increase of 145% over Regular shot.
U-E
Mark
Marks an enemy for ~5 seconds, the marked enemy will take 10% increased damage. Advanced XEN increases duration by 20% each.
H-A
Chain
Fires a near instantaneous velocity round that deploys a tesla spike at location. Deals random high damage to a random nearby enemy 18 times over 10 seconds. Damage calc works similar to Divine Might. A base hit with -43% power and a bonus from ~1% to ~84% of your attack power (record dmg in 72 attempts), with an average power increase of 3848% over Regular shot. No elemental build-up. Radius does not affect range. Very powerful with Advanced XEN (See Advanced Entry) as well as Turbine Barrel.
R-B
Heavy
Performs as a sniper. ~97.5% damage boost. Generally no bullet drop or damage falloff, tested at extreme ranges.
L-B
Spray Cannon
Fires near instantaneous velocity missiles without damage falloff from range with AOE of about 2m. Can't hit weakspots or crit. Around 180% damage boost on direct hits down to 46% at the edge of the AOE. Arguably a straight upgrade to 'Heavy' vs groups of enemies. Light Strikes only apply to direct hits.
R-A
Grenade
Fires a grenade that bounces and detonates on enemy contact or after 3.5s with an AOE of about 3m. Around 65% damage boost on direct hits down to -31% at the edge of the AOE.
E-A
Focus
Fires a beam up to 20m. Cannot crit or deal weakpoint damage. As long as the attack is held, gains ~7.44% power (based on initial hit at -90% power) each shot until 100 stacks. Caps at 744% bonus to initial damage, which is still 17.09% lower than standard shot of 'Regular' XEN Morph. Light Strike follows a lower curve, with 69% of the initial hit, but only increasing at a rate of ~2.38% power, reaching 238% bonus to the initial Light Strike damage.
U-A
Explosive Arrow
Fires an explosive projectile that pierces the target for 143% bonus damage on direct hit, exploding after 3 seconds for the same amount. The explosion has a radius of about 3m, comparable to the grenade. Slight curve at range, deals exact damage regardless of range or AOE position.
E-A
Elemental Ball
Fires an energy ball that lands on the ground then travels forward based on current player movement speed. Pushes away and hits everything it touches, can rarely hit the same enemy multiple times if it stays in the path after knockback. Reaches hardly 1m when fired without moving. With movespeed of 520 it reached; Walking:10m, Running: 30m, Running Slide: +70m. The distance is heavily affected by flat terrain, the ball falling off edges, and ends immediately if hitting a wall.
E-E
Cooldown Field
Creates an AOE at target for 10 seconds that increases firing rate (cooldown of Morphs, not skills) by 20% for anyone inside. Buff does not persist outside the AOE. Does not apply to the shot itself even if you are in range, only subsequent shots. The increased firing rate persists for anything fired until the next cooldown, so can be used to offset a lot of long cooldown Morphs. Advanced XEN increases duration by 20% each, despite the visual effect disappearing.
U-E
Harden
No way to test in firing range.
R-A
Beam
Fires a single beam that pierces everything up to 20m. Cannot crit or deal weakpoint damage. Claims booster XEN are applied only to the first target hit, but things that affect the damage or apply Light Strikes all seem to affect every target normally. The beam tends to fire at a higher trajectory than player is aiming when fired close range at a target.
R-E
Barrier
Little to test in firing range. Advanced XEN decrease the duration by about 20% each. (Bug?) *Supposedly damage increases will increase barrier duration.
R-E
Load
No way to test in firing range. *Loads 200 ammo per shot. *Scatter barrel triples the ammo loaded to 600.
E-E
Healing Range
No way to test in firing range. Advanced XEN increases duration by 20% each.
R-E
Adrenaline - Mobility
120 movement speed increase to targets within less than 1m of hit for 5 seconds. Restores about 40 stamina on hit. Advanced XEN increases duration by 20% each.
R-E
Adrenaline - Melee
30% increased melee damage buff to targets within less than 1m of hit for 10 seconds. Restores about 80 stamina on hit. Advanced XEN increases duration by 20% each.
TBD: Warp, Elemental Scatter Shot, Cluster Missile, Chain Reaction.

Barrel Interactions with Morph XEN (WIP)
https://steamuserimages-a.akamaihd.net/ugc/5841806006839924834/C0891295D7E110984242D9A2454A5614B56BB0FF/?imw=256&&ima=fit&impolicy=Letterbox&imcolor=%23000000&letterbox=false
Barrel + Morph XEN
Effect
Scatter Barrel + Pinpoint Strike
Scatter barrel lowers to x3*3, after reduced dmg is weaker. It is lowered further to x3*2 at close range. (Bug?)
Scatter Barrel + Gravity
Five hits (Pulls)(x3), then explosion.
More TBD.
  • Essentially seems that scatter barrel decreases the duration of duration based morph on top of decreasing the damage, which can really hurt the effectiveness of some morph by doubling drawbacks.
  • Need to test if similar is the case with Double Tap barrels.
Updates:
Update (4/16/2024)
Checked reported changes to Chain Morph. No longer gives inexplicably high crit multipliers, now it matches your crit bonus correctly. Also only gains 100% damage from Turbine Barrel charge instead of ~500%. Advanced and Multiplier efficiency bonus now gives flat hit increases, from 18 to 26, to 35, to 41 with three. Four or more does not increase hits from 41. Corrected buff values of airborne helm, it does actually give correct boost to attack (not damage) but still only stacks to 5, not 10. As previously stated. Multiplier max boost range is 40m, not 35m. Support Core Gun has been fixed.

Update (4/11/2024)
Many XEN retested, Booster categories reorganized and missing details added. Boosters that give additive vs multiplicative boosts distinguished. Tested the 'Advanced' XEN with every morph to discover some interesting effects. Turbine barrel added to guide and tested with some morphs (It is extremely powerful with Chain). Strong IV now correctly gives 25% damage boost. Terminology section added. Determined the likely damage calculation formula, unable to determine exact damage gained per attack point, as higher attack values result in a higher damage ratios.

Update (4/6/2024)
I have tested in great detail every Morph XEN I currently have access to, with damage comparisons against "Regular", and their costs and cooldowns referenced. As well as in depth breakdowns of the effects, ranges, radii, and synergies in detail. Categories marked 🔸

What is "elemental build-up" mean?
Noble Cataclysm 31 May, 2024 @ 4:56am 
Something I just noticed that's a bit random. If you use the efficiency mods on Gale, it actually reduces the time that the tornadoes exist of the field.
VinzMc 23 May, 2024 @ 7:44am 
Just a suggestion: maybe you can check each radius increase (%) by testing it on the shooting field using the cooldown field

Here is what I tried: https://imgur.com/a/pzOM3Go (hope this help)
The_Penance 7 May, 2024 @ 1:39am 
I would love someoen to test on Gale which is not listed here. It is extremely unpredictable and I wish i could get it to work better. Can't really do that unfortunately.
Stolen Kektus 6 May, 2024 @ 7:10am 
I'm volunteering to help collect data for Mend and Mend II, with their corresponding synergies and all. If that is alright with you, then I'll be happy to provide you with my research notes.
Weathnarh 4 May, 2024 @ 8:36am 
For the "Load" shot. it doesn't reload 200 ammo but twice the cost of the shot.

So if you put an upgrade so the shot cost 200 ammo to fire, it'll reload 400 ammo on the turret (1200 ammo with scatter barrel).

On the other hand. if you put upgrade that reduce the ammo cost. it'll reload less ammo on the turret.

Hi @Valkerion. Thank you for all this work, very inspiring! Could you give me the 4 Xen combos you would personally use?
Valkerion™  [author] 27 Apr, 2024 @ 4:43pm 
@The Vandalorian - Well you got me very curious lol. I can't see any typo in my math that would have got me 292.88, so I am not sure how that happened.
All other data I entered into spreadsheet with calcs but that section I just typed up as an example straight into steam, so I have no idea. Closest I could get was 292.404 which didn't explain the value I entered either.
