Traits

Legendary Resistance (3/Day). If the incarnate fails a saving throw, it can choose to succeed instead.

Magic Resistance. The incarnate has advantage on saving throws against spells and other magical effects.

Siege Monster. The incarnate deals double damage to objects and structures.

Actions

Multiattack. The incarnate makes two Slam or Energy Bolt attacks.

Slam. Melee Weapon Attack: +15 to hit, reach 15 ft., one target. Hit:27 (3d12 + 8) force damage.

Energy Bolt. Ranged Spell Attack: +12 to hit, range 120 ft., one target. Hit:32 (5d12) necrotic damage.

Planar Exhalation (Recharge 5–6). The incarnate exhales concentrated energy native to its plane in a 60-foot cone. Each creature in that area must make a DC 23 Constitution saving throw. On a failed save, a creature takes 52 (8d12) necrotic damage, and the creature has the blinded condition until the end of the incarnate's next turn. On a successful save, a creature takes half as much damage only.

Reactions

Searing Gaze. In response to being hit by an attack roll, the incarnate turns its magical gaze toward one creature it can see within 120 feet of itself and commands it to combust. The target must succeed on a DC 20 Wisdom saving throw or take 16 (3d10) fire damage.

Teleport. Immediately after a creature the incarnate sees ends its turn, the incarnate teleports up to 60 feet to an unoccupied space it can see.
