Umbral Dive

You step into your shadow, melding yourself and all the equipment you carry with the shadow for the duration. Nothing of your presence remains visible or otherwise detectable by nonmagical senses.

While merged with the shadow, you can see what occurs outside it. You remain aware of the passage of time and can cast spells while merged in the shadow. When casting a spell from your shadow you briefly reappear surrounded by an aura of shadow energy. You can use your movement to leave the shadow where you entered it, which ends the spell. You otherwise can’t move.

While in the shadow you can not be targeted directly by attacks or spells, but are susceptible to certain area effects, such as a blue dragon's lightning breath or a Fireball spell.
