Tarkanan Marauder

If the marauder is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, the marauder instead takes no damage if it succeeds on the save and only half as much damage if it fails. It can't use this trait if it has the Incapacitated condition.

The marauder casts one of the following spells, requiring no Material components and using Constitution as the spellcasting ability (spell save DC 17):

At will: Message

1/day: Disintegrate

The marauder makes three Aberrant Strike attacks.

Melee Attack Roll: +7, reach 5 ft. Hit: 13 (3d6 + 3) Piercing damage, plus 21 (6d6) Force damage if the marauder had Advantage on the attack roll.

The marauder teleports to a space it can see within 30 feet, appearing in a dazzling flash. Constitution Saving Throw: DC 17, each creature in a 5-foot Emanation originating from the marauder when it appears. Failure: The target has the Blinded condition until the end of the marauder's next turn.
