Your passive is way overpowered and needs a fix.

At level 18, one stack of your passive deals 80 true damage. This doesn't seem too bad, until you get 5 stacks off. This alone deals 1200 true damage (more than that effectively, assuming duration refreshes with each attack, and stacks are refreshed cumulatively), which is broken as heck.

A suggestion may be to remove the level scaling and use the increment at set levels (x damage at level 1, x damage at level a, etc).
