What are Nether Powers?

Nether Powers are powerful passive or triggered effects rolled on Netherfused gems. Socket the gem into a matching Netherfused socket to add its power to the weapon.

On an awakening-enabled Unique weapon, the power scales with the weapon's awakening level.

How do I re-roll a Nether power?

Netherfused gems cannot be rerolled directly. Smelt an unwanted gem to recover part of its materials, then craft another gem. Socketed gems can be freely removed or replaced at a Runic Forge.
