While in the catacombs my group was facing Vassar and Ralena we were attempting to pull one of them from their room into the hall to the north and then to shut the door behind that one to keep the two separated.
We were having some difficulty at this and I noticed my necro skill “Spectral Grasp” and thought to use it to pull one of them through the door with it. I discovered that there are some vertical axis issues with this skill. Tho the issue I am mentioning here is the one time we did get one pulled into the room I attempted to pull them further up the ramp which caused them to be pulled through the ramp floor and then the entire encounter reset.
