The Destroyer
I mean featherfall as a set bonus is cool and all up until you get to a point in the game you need to upgrade your armour and you're too used to featherfallWhat if, instead of fall-damage reduction, the armor set gave a featherfall-type effect? This itself would reduce fall damage by extension, and then even after a source of fall damage immunity is obtained it would still be fun to use.
