The Angel in Lv. 8 Boss is bad design, really BAD!
He just keep giving barrier and sanctuary to himself and using DOT to torture player. You have to use 2 rounds to break 2 barrier but he just give himself 2 shield for 1 round. Same as immune but worst, there is nothing you can do but watching it torture you and gain 2 barrier AGAIN.
My berserker build cannot deal 1 damageto the angel and nothing I can do other than praying it can kick me instead of using any skill.
