Cloak of shadows (channel divinity)

Cloak of shadows was a channel divinity power granted to clerics of the Trickery domain.

Effects
A cleric with the Trickery domain could turn invisible or until he or she attacked or cast a spell.

While a turn of combat lasts an estimated 6 seconds, the PHB does not at any point mention that this effect only lasts one turn, and does not say that it lasts 6 seconds out of combat.

Components
Only the cleric's skill was needed to evoke this power.
