Cloak of Imperceptibility (Z)

Dexterity: +2 up to a maximum of 22.
While you wear this cloak with its hood up, you
gain advantage on initiative rolls and Dexterity
(Stealth) checks made to hide as the cloak's color
shifts to camouflage you.
During your first turn, you additionally gain
advantage on your first attack roll against any
creature that hasn't taken a turn.
Pulling the hood up or down requires an action.
Requires Attunement — Zenith Artifact
