At the end of the Brakion strike, you have a chance to die at stage 3 of the boss (Where you knock off his head and he chases you) If you die your teammate has to revive you. 70% of the time, Brakion will be close to you, therefore, resulting in a stomp. There's very little you can do to recover from a stomp. The worst part about the knockback is, when you get revive you can't move for a while but you can still get hit, so Brakion will stomp you off the map while you're in the revive animation
