So now my cavalier has gone from getting _nothing_ from levelling up to getting "+-16" health every time. It's been a problem for so long, but nothing's being done about it...tisk tisk!
Not sure if anyone else has mentioned this, but BEWARE using Terror on a boss...I had one run through the wall and roam the edges of the room. I was unable to kill it or leave, so I had to reload the page and lose my unsaved data. BEWARE!
