Achievement: Phase-Lost-and-Found

Notes:

This phase-affected slateback is the reward for the achievement, Phase-Lost-and-Found, which involves finding all 27 Phase-Lost item appearances in K'aresh. These appearances have a small chance of dropping from phase orbs which can only be seen during Phase Diving, and only after you upgrade your Reshii Wraps cloak with the 'Secrets of the Depths' talent. Phase orbs can be found in the zone and also after you defeat enemies. See Wowhead's phase diving transmog guide for more information.
