After some testing with the new mythic, I noticed a game breaking bug that prevents Dark Deal from finishing it's channel and giving resources and a heal.
Here is how you can recreate the bug:
1.Hold block while wearing Syrabane ward
2.Activate Dark Deal from the Dark Magic skill line
after activating the skill while blocking the animation will play but will hold and refuse to complete - not allowing the player to heal themselves or gain resources. How to fix the animation is rather inconsistent. Sometimes swapping bars will fix it but that worked 4/10 times I tried it. Sometimes the channel randomly goes off after an extended period of time has past.
