I’m talking about this prefix.
As it stands right now this prefix is just a weaker version of the modifiers on Herald of the Apocalypse. While the removal of Devastation’s energy cost is nice, it’s not particularly useful. With that said, here’s my suggestion: change the fire damage to cold damage, and replace the skill cost reduction with 100% cold damage converted to fire damage to Devastation. This is something that used to exist on the Diviner set, but with the recent set redesign it was removed in favor of fire to vitality. While I think this was a positive change for the set, it did remove the option of cold Devastation builds. Implementing my suggestion would restore this option, and make this prefix significantly more useful than it is right now.
