What do Acid & Venom Abilities fall under, if allowed?

[MysteriouslyMaple]

I don't see an issue with characters having mutations where they can spit or spew acidic material, like the example you gave with the ants and beetles. But in regards to some chemicals being flammable when exposed to a certain substance, I'm going to say no to that one, unless fire elementals was bought - in which case, yes, you could say that having metal teeth or something similar enables them to breathe fire. Just not without the item, sorry about that!

I hope that was able to answer your question! If not, I can ask Egg or Orion for clarification on whether or not it would be allowed :0
