Growing Power on Sevagoth breaks the attack animations on Sevagoth's Shadow.

[CitizenKing]

Just finished testing it in the Simulacrum.

With the Growing Power on Sevagoth, Sevagoth's Shadow doesn't swing its arms at all.

I replaced the aura on Sevagoth with something else (Steel Charge) and sure enough the arms started swinging again.

I put Growing Power back on Sevagoth, Sevagoth's Shadow's animations broke once more.
