Elixir Container Mod suggestions:

A mod, or possibly even a new elixir, might be one that heals through regeneration style healing? The way I'd first mentioned it would be something that causes regen to tick once a round, lasting as long as you still have toxicity ticking down from the use of the elixir. Now, I've been told that there is no system for checking this currently in place, so perhaps a timer, instead. Perhaps regen 1 to 3 for a minute or something like that, with the amount that regens increasing as it goes up in level, say, it being regen 5 at level 100, or lasting for 5 minutes at that level. Not sure of possible materials yet, but perhaps something from lycanthropes or raptors and snakes.
