Avatar of Semunaya

Humanoid heart. The avatar has a humanoid suspended in place of it's heart, the humanoid who channeled the god. this humanoid is unconscious, but can be attacked. it has AC 25, and a hit on the heart causes the humanoid to automatically fail a death saving throw, and is an automatic critical hit on the Avatar. The humanoid is suspended 30 feet in the air,  where the avatar's heart would be. the humanoid does not roll death saving throws while inside the Avatar, but when the avatar is slain, the Humanoid falls out and makes death saves as normal.

Brave. The avatar has advantage of saving throws against being frightened

Siege monster. the avatar deals double damage to objects

Spiritual nature. the Avatar does not need to eat, drink, breathe, or sleep. Other creatures can pass through the Avatar's space during their turn, as the Avatar is somewhat intangible, but creatures that end their turn inside the avatar(other than the avatar's heart) are pushed out to the nearest unoccupied space and take 1d10 force damage for every 5 feet traveled. they exit prone.

The target must make a DC 15 dexterity saving throw or else take 59 (6d10 + 26) phychic damage and be frightened of the Avatar until their next turn. they take half damage on a successful save.
