Offhands
Offhands are powerful items you hold in your second hand to grant an active or passive edge — a burst of fury in PvP, a mining boost in the mines, or an extra trick on the Hunt.
Each one ties into a different system, so the right offhand depends on what you're chasing. Many are tied to bosses and other endgame content; see the entries below for what each does and where it comes from.
