Is this a glitch or a boss thing? I was taking on Chaser Keser, and was going to use shield rush to get rid of the mobs around him since I was soloing. I go to press the button, and all my SP is gone (I had four full bars).
This has happened one other time to me when I was doing fleeing gnoll king, although I was in transformation at that time. I thought it was a transformation glitch, however with it happening on a different boss with no transformation, I'm thinking it's just a general glitch.
A very annoying one at that.
