Reported this in-game, but want to report it here as well just in case.
The Stay of Execution channel will fire off the attack after one attack as expected, but holding down the attack will continue the channel for several seconds doing nothing before it finishes with the actual attack animation, but not the attack. Sometimes I’ll also get stuck in a t-pose and rapidly spin in place afterwards.
The mutilate node seems to consume all bleed stacks after each attack instead of every third, or at least what I see is bleed stacks on the enemy never increasing past 1 when this node is taken, but easily going to several stacks with a single attack without it,
