Short description

This PR improves underutilized and otherwise weak abilities and nerfs the broken fleshmend by locking it behind 2 organics absorbed. Also adds a doubled rot timer for ling victims or something.

Why we need to add this

Changelings kinda suck to play. They also suck to get eaten as since if you aren't found in time, you'll just be rotted and soft RR'd. This PR will hopefully alleviate some of this issue by doubling the rot timer for ling victims. Also balances some ling abilities.

Media (Video/Screenshots)

Fleshmend changes
fleshmend-changes

Shriek changes
https://github.com/user-attachments/assets/0652814d-e6ca-4b76-b726-851d5e1c8569
The shriek will no longer flash yourself (why did it do that in the first place?) and will ignore flash protection. It's a shriek, not an actual flash! (EDIT: removed the flash protection immunity)

Invis changes
https://github.com/user-attachments/assets/7a3a2faa-eae2-4b5c-94ea-559f8631c33b
The invis ability will now last twice as long as the drain while being invis is now halved.

Absorbed victim changes
https://github.com/user-attachments/assets/23c7a582-b868-4978-935f-762d57192853
Ling victims have a new inspection text to reflect the new increased rot timer.

Rot timer reset
https://github.com/user-attachments/assets/f3ce1b4b-f4b6-4364-baf4-ec60e626c042
When the victim is revived, their rot timer is reset so you don't continue to rot twice as slow even if you died to something else entirely later in the round.

Changelog
🆑 Turk1shcat(_Plunger)

  • add: Ling victims now have an increased rot timer, effectively giving you twice the amount of time before you fully rot.
  • tweak: Changeling fleshmend now requires you to absorb at least 2 victims to use.
  • tweak: Changeling chameleon skin (invis) now lasts twice as long.
  • tweak: Changeling resonant shriek no longer flashes yourself.

📝 Summary

Summary

This PR updates changeling abilities and absorbed-victim rot behavior.

  • Fleshmend requires at least 2 absorbed organics.
  • Chameleon skin lasts twice as long and drains fewer chemicals while invisible.
  • Resonant shriek no longer flashes the changeling.
  • Absorbed victims receive updated rot timers and examination text.
  • Reviving an absorbed victim resets its rot timer.

Notable implementation changes

  • SharedRottingSystem.SetRotAfter updates PerishableComponent.RotAfter.
  • SharedFlashSystem.FlashArea supports ignored entities.
  • Changeling logic resets rot timers after devouring and revival.
  • Changeling configuration and localization include the new requirements and text.

Gameplay impact

Fleshmend requires prior biomass collection. Chameleon stealth provides longer invisibility with lower drain. Resonant shriek does not affect the changeling. Devoured victims receive a 20-minute rot timer, while revived victims receive a 10-minute timer.

Risk areas

  • Removing the changeling’s self-flash may increase Resonant shriek spam potential and reduce counterplay.
  • Rot timer changes depend on PerishableComponent availability and state-transition timing.
  • The 20-minute and 10-minute timers must match the intended gameplay design.
  • Changes to shared flash APIs can affect existing callers.

Guideline gaps

  • The PR context does not explain why revival uses 10 minutes while devouring uses 20 minutes.
  • The PR context does not state whether the shared API changes follow Shared-first and Starlight ownership conventions.
  • The PR body does not describe the intended counterplay for Resonant shriek after removing the self-flash.
  • The PR context does not explain the rationale for the changed Chameleon duration and drain.

Walkthrough

Changeling absorption now updates perishable timers. FlashArea can skip selected entities, and Resonant Shriek bypasses flash immunity while excluding the changeling. StealthDrain, Fleshmend requirements, and changeling localization text were updated.

Reduced StealthDrain to 1.25f. Fleshmend now requires two absorbed biomass units. Added examination and ability text.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to bd6c4

The PR changes changeling ability behavior and absorbed-victim rot timing, but protected targets may still be unaffected by Resonant Shriek and death transitions can shorten the intended extended rot window; related localization and documentation changes also need cleanup. These bounded correctness and integration issues should be fixed or explicitly accepted before merge.

The shriek will no longer flash yourself (why did it do that in the first place?) and will ignore flash protection. It's a shriek, not an actual flash!

This is completly busted, there is no cooldown to it allowing it to be spammed without any kind of counterplay from anyone on station. Even ERT/Marine wont be able to deal with a ling using shriek and a basic armblade/gun.
You spam it it while meleeing/shooting and there is nothing anyone can do. This is just broken balance wise.

Dont ERT/Marines have their own flashes... just use a flash when you get flashed.
