Additional Information

An enforcer's honor can be a prickly thing. So can his quills.

Notes:

Deals damage as it quickly expands outwards. (at 2400 speed)
Quill Spray damage is not reduced by damage block abilities. (such as Vanguard, Kraken Shell.)
Stacks are independent, not refreshing, which means that normally Bristleback can deal at most (14 seconds duration / 3 seconds cooldown) 120 bonus damage. To reach the damage cap, additional Quill Sprays from Bristleback passive are needed.
The stacks cannot be removed by Purge or other buff removing abilities such as Kraken Shell.
13 / 12 / 12 / 11 stacks are required to reach the 450 damage cap, which so require 9 / 8 / 8 / 7 sprays from Bristleback (which takes 2500 / 2250 / 2250 / 2000 damage taken from the rear), since only 4 stacks can be achieved with Quill Spray alone.
Has an instant cast time.
