Neptunus Synergies

Description
Pretty lame that such an interesting item doesn't work with tear modifiers. Since it also is a planetarium item, that had to be fixed.
In case Repentogon is installed, mod uses it's features for new/improved synergies.
Some little customizations, alike not applying custom sprites, can be made through Mod Config Menu or Rgon's ImGui.
Synergies
  • Ludovico Technique: when you're not moving your tear, tear's size grows up to 2.5 times; while moving, size decreases back to normal.
  • Monstro's Lung: additional tears are fired, amount depends on Neptunus charge.
    Repentogon: makes Lung work tear-alike, shortening charge time.
  • Technology: works like normal Neptunus; visually changes lasers to look tear-like; if you have charged attack, instead widens laser depending on Neptunus charge.
    Repentogon: Chocolate Milk now works like vanilla Neptunus + Chocolate Milk synergy; also works for familiars that copy your attack (e.g. Incubus).
  • Tech X: widens lasers depending on Neptunus charge.
    Repentogon: instead, charge time of your attack is shortened; also while player has some Neptunus charge, autoshoots upon reaching max charge.
  • Brimstone: increases beam duration up to 5x depending on Neptunus charge.
  • Dr.Fetus: works like normal Neptunus + bombs leave blue creep.
    Repentogon: also works for familiars that copy your attack (e.g. Incubus).
  • Epic Fetus: fires many tears, that deal 0,66x dmg; amount of tears depend on player's Tears stat and on Neptunus charge; bombs leave blue creep.
  • Mom's Knife: depending on Neptunus charge, 0 to 3 water (pseudo-)knives are launched for each knife.
  • Spirit Sword: sword's swing attack is transformed into single spin attack, if you have enough Neptunus charge.
    Repentogon: transformation is performed better: attack reflects bullets correctly; also has hitbox of normal size, without extra sprite enlargement.
  • C Section: fetuses also fire tears(0.4x dmg) in direction they are facing.
    Repentogon: instead, charge time is shortened.

  • Forgotten/Berserk: after normal attack fires huge piercing tear, that deals up to 3x dmg, depending on Neptunus charge;
    After shooting bone, near peak creates splash (0.5~3.5x dmg), both size and damage depend on Neptunus charge.
This isn't full list of synergies - check more full list of synergies here[docs.google.com].
Also, standalone version with only non-rgon versions of synergies is available.
Huge kudos to JamesB456, whose mods were taken as inspiration.

@Professor Greanbeans I've created separate version with only non-rgon synergies, link

Not at all!

@Professor Greanbeans never thought anyone would possibly need that, lmao.
Would you mind to move this to pm?

Is there any way to get those older features while having Repentogon?

Mod works with rep+

Question here, you gonna update for rep+??
Roary  [author] 20 Nov, 2024 @ 12:19am 
@RDW, why not ask James himself first?

Anyway, I won't do this as:
1) to me, that would feel as stealing away from him;
2) combining everything in one mod is not good idea most of times.
Roary  [author] 19 Nov, 2024 @ 11:50pm 
@Ludwig_Lavender, as much as I've tested, mod doesn't need rep+ update.
RDW 19 Nov, 2024 @ 7:20pm 
Hello there @Roary! I have a question for you. Will you make a compiled remaster of JamesB456's synergy mods that combines all of them into one, has additional features with Repentogon, adds synergies that were never ultimately added like Epic Fetus + C Section, make balance changes to already existing synergies like Epic Fetus + Glitter Bombs, and fix that one weird bug with Fiend Folio's Angelic Lyre when it comes to the Dr. Fetus edition? I'm asking you this because based on the fact that none of James's mods haven't been updated since 2022 or 2023, I'm gonna assume he's done with Isaac modding and possibly the game itself in general. He's still alive and on Steam, just more focused on Dead by Daylight nowadays

Update mod for Repentance+ please
