Fact of Nature - Demon has a flip skill called True Nature - Demon
True Nature - Demon has 600 radius which is absolutely massive
True Nature - Demon is unblockable (doesn't say so on the tooltip) (tested)
True Nature - Demon ignores blinds (doesn't say so on the tooltip) (tested)
True Nature - Demon ignores EVADES, something very few skills does, doesn't mention it on the tooltip either (tested both with dodges and the thief elite (for easy timing))
True Nature - Demon has 1/4 sec casttime and almost no animation, not that it would matter because you can't actually dodge/blind/block it
The only thing that actually avoided it was hard invulns (tested with guardian elite)
Give it a 240 radius, 1/2-3/4 sec casttime with an actual animation and make it at least evadeable.
At the moment you can get hit for 50 torment just from this 600 radius unavoidable skill, it even has a flip skill that allows the herald to gather up condis in the first place.
