Something with sufficiently fast regeneration could actually push stuck-ins out of wounds as they heal.
As projectiles.
Reminds me of that scene in Time Bandits where the English Longbowmen fire arrows into the Devil. Good idea, bad result.
Quote from: Greiger
"Made me think, will it be possible to make a creature immune to certain diseses?"
(From Toady): "For the poison effects that are currently in, you add in affected classes and then immune classes, and when other diseases go in I don't think it'll be handled differently, unless poisons have become more refined by that time."
One idea to possibly handle diseases and immunities would be to have a set number of possible diseases in a given world, with defined effects, means of spreading, preferred/compatible biome, etc.
You could then assign them a percentage chance (like from 1 in a million to 1 in a hundred), per year, that they'll evolve to effect
any given species (whether it's a dwarf, a rat, a dragon, a beetle, a bluejay, whatever).
Once they've made that jump, they might then have a 10x greater chance of affecting another species that's in the same group as them (as in "animal", "humanoid", "fanciful", "vermin", etc.). The cure could either be predefined per disease, or selected randomly at the beginning of every game.
I know it's not 100% biologically accurate, but it seems like it might work, and be reasonably easy to add to the game.
