About Tal Rasha's Horadric Crest

It's part of the full set Tal Rasha's Wrapping. It can be used by a variety of builds, such as Tal Rasha's Full Set for sorceress, or physical builds because of dual leech, and mercenaries. It can be dropped from early Nightmare and the required level 66 is not high, making it a very good helm from mid game to end game.
