Big Foot Poison Intended?

Poison doesn't heal Bigfoot. Disregard the numbers. Poison does what, 2.5% of the monster's hp per second? That's 800,000 damage per hit. Apparently poison damage isn't read in the same way as other skills. It's probably stored as a 16 bit integer and rolls over whatever the cap for the damage is several times.

That's also the reason why you can take poison damage from enemies even if you've been touched by them.
