Fade is a temporary aggro reduction that can be used in parties. Its basic function is to reduce all Priest-generated threat for the duration of the spell, taking the Priest off the top of the threat list. This allows a priest to use Fade to get enemies off of them while they heal their party members.

How much does fade reduce threat?

Fade (Rank 7) reduces your threat by 1500 for 10 seconds and does not affect threat generation. Each point of damage dealt is roughly 1 threat.

Does fade drop combat?

Notes. Fade itself is not useful in single combat, in sneaking past enemies, or in escaping a target while not in a group. Fade only reduces your threat relative to the mob's other possible targets.
