Intolerance
Make the opposite intolerance lead to their associated categories (Meat Intolerance -> Herbivore, Hates Vegetables -> Carnivore). No, Saprovore cannot come from lactose intolerance, but I suppose you CAN argue junkfood intolerance does (processed food with preservatives vs rotten). Right now the traits intolerance/hates are actively working to cancel out progression in certain ways regardless of what sort of dietary trait it is. This makes no sense, particularly that they’re supposed to be negative traits. Or make them a separate line with “x rejection” being the next logical progression.
Health
Add tough to post-threshold Cattle and Ursine. Add durable to Lizard in post-threshold. Give Chimera Unbreakable in post-threshold. Strength compensates decently for having an increased health total. However, it feels more appropriate to have those groups have them. Chimera also has absolutely massive problems. In the case of Lizard, it’s simply because it feels a little weak right now.
Slime
Replace Hollow Bones with Light Bones and Thin Skinned in Slime. Melting bones do not translate to hollow bones. Omnicellular: Having an average decreased health total (sum of limbs/head) but giving a single large health pool. My pre-edit suggestion was making limbs grow back and having headshots be nonfatal while decreasing total hp by either 25% or 50%.
Alpha
Add junkfood intolerance. Add the unique trait about “Absolute Perfection” which causes you to suffer morale penalties for having your stats negatively affected or being actively sick (coughing/vomiting), but grants a good bonus to social interaction. Alpha just feels a little strong and is focused around being absolutely perfect. While this may strike envy in nonmutant NPCs, you can probably use it as social leverage.
Elf-a
Downgrade Radioactivity, Disintegration, Hollow Bones, and Vomitous. Add Lightweight, Junkfood Intolerance, Meat Intolerance, Mood Swings, Frail, and Lactose Intolerance. Make Fey Eyes and Full Night Vision a prerequisite for Fey Nightvision. Remove Fey Nightsight from existence. Creating mutations that are functionally identical is pointless, unless you are specifically trying to create stacking or don’t want people avoiding it by simply purchasing that negative attribute in character creation. “An attempt at hybridizing mutagen lines to remove negatives and make them more useful. This has had mixed results.”
Chimera
Give Chimera both Fast Healer and Disintegration. Add Regeneration to post-threshold. Having mutations that cancel each other out with Genetically Unstable feels very appropriate for this mutagen line. I’d like to see Genetically Unstable become a fixture of the line along with something akin to Extreme Mutation. Instead of “progressing,” traits are instantly adapted instead of moving up or down one grade. The rapidly changing feature of Chimera is something I’d like to actually see made.
