Instead of granting invisible when an enemy is killed it grants (or also grants) invisible at the start of combat. (Pariah) At least to the mobs
The on-enemy-death effect happens in addition to starting battles with invisibility, for both enemies and the player.
starting invis is pretty neat to negate agile. since i dont yet have access to nightmare golem and not too grindy to try to roll its material. though i guess it will be fixed since it looks more like s2 legacy
