We’d also prototyped a skill codenamed “Infernal Sweep” which was a fiery subject of effect sweep assault that burst nearby corpses. Early testing showed it felt bad to use, needing to poe trade swing two to kill some enemies then again to detonate their own bodies for bigger area damage. The ability was visually spectacular, but didn’t play well unless it had been boosted in the beginning place and damage to the point where it invalidated the roles of Sweep and Infernal Blow. This skill went back to the drawing board and we’ll likely see it in future with added mechanics or without the dependence on corpses.
