Volibear's E Makes Jungle Monsters Ignore Damage

How to bug: Walk up to Jungle Camp, do not hit it Majestic Roar, be sure it was the first thing to touch the camp Start attacking Monsters while they are feared Notice the camp's HP regening as if it lossed aggro/isn't in combat

Can get especially grievous if you Roar while your Bot Lane is leashing you. 3 seconds of "oops, that didn't work, can you stay with me a bit longer?"
