I’m a little confused with how poison stacks in this patch. I haven’t played it much yet (and I don’t have a strong poisoner on hand currently), but I thought it first meant 5% Attack per turn per stack, so at 10 stacks you have 50% of the attacker’s Attack per turn, but it sounds like every application also adds more attack to the “pool” that it scales off of, so attacking three times to reach 10 stacks effectively makes you do 150% of your attack power per turn?
It has been changed in a hotfix:
Poison deals damage based on 5% of the inflictor’s Attack multiplied by the number of stacks. If another creature or spell inflicts the target with Poison, the Attack value is only changed if it’s higher than what is already applied.
