Poison sanity
Poison, Stoning Poison, and Deadly Poison, on merge automatically set their max power to 5x the power set by default. This means that their damage cannot stack more than 5x times unless explicitly specified.
Poisonous Bite is an unarmed attack (prevents stacking of weapon bonuses with its built in multiplier).
Nerfed Toxic Death Radius slightly. These changes will hopefully control potential runaway poison spreading.
