How? Until you specify, I'm not going to count your attack. However, I will store 50 points of damage since that's the normal damage of such an attack.
I poison you by biteing you obviusuly, it should also do dammage over time.
I'm just speeding it up by applying that damage all at once. You deal 50 damage as stored. Also, the snake armatar is currently broken, which is why I made you specify.
