About The Pull Request
Added two new traits, TRAIT_NOMETABOLISM and TRAIT_TOXIMMUNE. Does what it says on the tin, making livers not process reagents at all (except liverless reagents) and gives immunity to toxin damage. Species with NOMETABOLISM spawn with no liver (NOLIVER is now redundant and has been removed). This trait also prevents liver failure damage, for obvious reasons.
These traits have been given by default to androids (artificial, they were already immune to chemical healing anyway), zombies (who have their own regeneration) and skeletons (milk still works).
Other changes:
Species' handle_reagents proc now fires before checking for metabolization, so species can process chems even when liverless.
Removed the calcium healer trait, making it into a species handle_reagents check for each affected species (skeletons, plasmamen, bone golems). Skeletons now also heal burn damage from milk, since it's one of the few forms of healing they have available.
Note:
These traits should logically be applied to plasmamen and golems, but i intentionally left them out for now since it would be a significant balance shift, and there should be a proper alternative way of healing them first.
Why It's Good For The Game
Balances the significant benefits of being undead with a significant negative: being immune to chemical healing. Since zombies don't really rely on it and androids were already heal-immune, this mostly affects liches, and i believe it should be fine: considering that the main point of the spell is the resurrection mechanism, the space, gas, pierce, and heat/cold immunity they also gain should be counterbalanced by having a harder time recovering from injuries.
There is also a silver lining to having this trait: poison immunity. Effectively this is a buff to androids and zombies, the latter especially because they can no longer process mutation toxins. While this tactic is creative, it also trivializes a very expensive investment of TC. I might still add a liverless way to apply mutation toxins later on, but zombies shouldn't be effectively one-shot by a syringe gun.
Changelog
cl
add: Androids, skeletons and zombies no longer metabolize reagents. As such they no longer benefit from healing reagents, nor are affected by poisons and toxins.
add: These species are now also immune to any other form of toxin damage.
tweak: Milk now also heals burn damage for skeletons.
