Hi, my wife is leveling towards chaplain and I went to do some research on chaplain skills. This skill is very bad to use and aoe is pathetic.
Magnus Exorcismus should be top tier damage spell, as the name says.
I recommend from bottom of my heart that you make it so that Exorcismus square has fadetime of 2-3 seconds so u can drop it on enemy and then cast magnus exorcismus, instead of now instantly disappearing when touching enemy.
I also recommend that u make the spell aoe bigger, or add another set of pillars in cross shape.
