Void Song. Every three turns, the Angel will cry a harrowing song. This screech blinds and deafens all characters for one round.

 Spellcasting: 

After at least 1 health segment has been destroyed, they will gain a few more abilities:

Void Fog:

A surrounding fog that heals the Angel if it damages a character, dealing 1d4 damage.

Purge: 

A delayed explosion that blankets a large area in the same radius as Void Fog.

Void Dash:

A teleport during which Angels are invulnerable. They will target the area around a character and, after a short delay, slam into the ground, creating a shockwave. Their landing zone is telegraphed by faint red energy swirling in the selected area.

Void Manifestation:

A slowly charging orb, which absorbs incoming damage and will home in on a character once thrown. The orb can be destroyed by, either in mid-air or while it is still charging. The latter causes the Angel to be staggered.

• A ground slam that sends out spikes in a line. If these spikes hit a character, they will be impaled, and the character's AC is set to 10, ignoring all other modifiers. They will not be able to revert this until they destroy the spikes. Spikes deal 1d6 damage and cause the victim to bleed.
• The Angel swipes a large area with its "wing." Deal 1d8 damage.

This monster is extremely slow, and does not get bonus actions or attacks of opportunity.

Retreat to the Void: 

The Void Angel opens a small pocket dimension and transfers it's spirit to there. If a character enters through the orb that is summoned, they can only damage this ethereal version using magic attacks. If the Angel is not dealt 5 points of damage, it begins to regenerate health to it's physical form, reverting it's health back to maximum. If the Void Angel is dealt 5 points of damage, it's spectral version returns to the physical body and the battle continues.
