Mutations available to players should never exceed a certain threshold. Mutations should be more about making a character sub-human, rather than super-human.
If a mutation will affect you so strongly that your base race is no longer discernible, it is not acceptable for play as a character. Your base race must be READILY apparent in both your short description and your main description. Mutant is no longer acceptable as a short description keyword.
If a mutation might otherwise be deadly towards you (translucent skin), or give your character a severe power increase (laser beams from your eyes), it is also not acceptable.
Being a mutant may dramatically change your social standing, but it in no way changes the culture for your race. Mutant dwarves still operate like normal dwarves, and mutant halflings still eat you.
While mutations are more prevalent in some areas, they are by no means the majority of any civilized population. Minor cosmetic mutations (extra finger, mismatched eyes, mottled skin) may be applied for in any standard application. If a mutation would have a noticeable effect on a character's lifestyle (claws instead of fingers for instance), forcing them to adapt differently to mundane activities like eating, holding weapons, ect, the concept must be applied for with a special application.
Mutations that give an advantage (armor plating, stat boost, infravision) may be allowed through a special application, though each will be closely examined for potential imbalance and abuse. Beneficial adjustments will only be accepted if they are coupled with appropriate disabilities. Ie, armor plating without the ability to wear normal armor.
This will be unsticked; you can now find it in "help mutant roles" in-game.
