I'll try to explain how you can make simple .ini edits to change the way most of the abilities work:

First we go into the mod config folder:

\steamapps\workshop\content\268500\1537495115\Config

There are 2 different .ini files which control the ability and weapon bonuses:

To alter the way abilities work:

XcomGameData_Skills.ini

To alter some of the damage tables used by specific abilities like Half-Sword and Warden's Tide:

XComGameData_WeaponData.ini
-

Let's start with abilities:

Foresight
Foresight essentialy creates a shield which gets destroyed after taking a certain amount of damage.

WardenForesightHPMult=1f

Foresight creates a shield around the warden, and as it does that it takes two things into account: The current HP of the warden, the HP of the warden when you've started the tactical play. It uses whichever is the greater number, multiplies with WardenForesightHPMult and uses that.

So essentially you can change that to 2f and create a shield twice as strong. Or if you think its too powerful change it to 0.66f and create a shield that is equal to 2/3 of the Warden's max health.

WardenForesightLastsFor=1

You can adjust this to make the shield last longer than a turn.

WardenForesight_DestroyOnDmgCond=1

This acts like a boolean. 1 means "I want the shield to get destroyed when I take damage". 0 means "I want the shield to last for its full duration no matter the dmg I take."

(If you wildly alter the amount of turns the shield can stay active and not get destroyed the vfx might not be able to keep up, I've created this abilitiy as a 1 turn thing. However the option is there for you to turn the Warden into some ungodly bubble monster)


Parting Strike
It is referred to as WardenBladeshredder in the .ini file. There are two parts:

WardenBladeShredder_BonusAim=10

This is the bonus Hit chance the ability grants to your weapon.

I suggest you scroll down to a section named [WardenClass.X2Effect_WardenBladeShred]
there are multiple different options you can change.

WardenConventionalShred=1
WardenMagneticShred=2
WardenBeamShred=3

These are how much armor you want to shred depending on the technology you have, pretty straight forward.

WardenBladeShredder_BonusDmg=(Damage=1, Spread=0, PlusOne=0 ...

This is the damage table it uses for the extra damage, it had to be applied this way because some of the abilities Warden has use invisible weapons that are not apparent to the player.

As a bonus however you have some extra options here, Instead of using a constant number you can make adjustments like PlusOne=0 to PlusOne=20 for example and you'll have a 20% chance to apply 2 damage. I suggest leaving the DamageType alone however as changing that can cause weird interactions with Mutons or Sectoids who have counter-attack and melee vulnerability.


Unwavering Concentration

ConcentrationLastsFor=2
ConcentrationCooldown=1
ConcentrationDefensiveBonus=5
ConcentrationDefensiveCritDmgBonus=1

Pretty straight forward, however ConcentrationDefensiveBonus=5 will apply that number to both the Hit and the Crit Chance. so if you have adjusted the +Hit chance to 5% and +Crit Chance to 10%. Those numbers will become 10% Hit Chance and 15% Crit Chance. That is important to keep in mind.

Scroll down and you'll see:

[WardenClass.X2Effect_WardenConcentration]
ConcentrationCritChance=10
ConcentrationHitChance=10
ConcentrationBonusCritDamage=1

These are the base numbers Unwavering Concentration applies during Offensive Stance.

Ebb and Flow

It is referred to as WardenDecider in most of the code, it is the ability that handles stance changes. If you scroll all the way down you'll see the section:

[WardenClass.X2Effect_WardenDecider]
+DeciderAbilities="WardensAdvance"
+DeciderAbilities="WardenPremonition"
+DeciderAbilities="WardenConcentrationActivate"
+DeciderAbilities="WardenHalfSword"
+DeciderAbilities="WardenWinding"
+DeciderAbilities="WardenPush"

These are the abilities which trigger stance changes, you can remove mine from here and add yours if you wish. But there are a few things you should be aware:

-It'll only accept template names, not player-facing text.
-Abilities that are turn-ending are not allowed.
-If you want them to be available in defensive stance you must add a Momentum Action Point to your abilities allowed action point cost.


I think the other options are way too straight forward so I don't want to bore. If you've any questions don't be shy.
