Poison

Poison is a new status effect that can be applied that deals continuous damage. For each stack of poison, an enemy will take 1% max health damage every half second. Each stack of poison lasts for 10 seconds. Applying new stacks does not refresh the time each stack is applied. (Scope for introducing poison: 4 hours)
