I am curious to know how extra poison types would be dealt with beyond neurotoxin. Creatures cannot be poisoned with neurotoxin, and players cannot be poisoned with aflatoxin, so there is currently only one possible non-"vanilla" poison type for any target. Throw in a second, and a question arises: if a player is inflicted with both neurotoxin and strychnine, what happens? Does the second poison type overwrite the first, or fail to apply? I doubt Zanz would consider using two icons to denote both poison types at once.
