Magic Maw: The eater of dust's Maw-Arm attacks are magical. When the eater hits with its Maw-Arm, the weapon deals an extra 3d8 necrotic damage (included in the attack).
Regeneration: The eater of dust regains 5 hp at the start of its turn. If it takes fire damage, this trait doesn't function at the start of eater's next turn. The eater dies only if it starts its turn with 0 hp and doesn't regenerate.

Multiattack: The eater of dust makes one Maw-Arm attack and two Necrotic Blast attacks, or it makes three Necrotic Blast attacks.
Maw-Arm: Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 12 (2d6 + 5) piercing damage plus 13 (3d8) necrotic damage, and the target must succeed on a DC 17 Constitution saving throw or its hp maximum is reduced by amount equal to the necrotic damage taken, and the eater regains hp equal to that amount. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hp maximum to 0.
