Multiattack

The edimmu makes two Draining Touch attacks. If both attacks hit one creature that isn't a Construct or Undead, the target must succeed on a DC 14 Constitution saving throw or suffer one level of exhaustion. A creature that fails this saving throw by 5 or more is also stunned until the end of its next turn.

Draining Touch

Melee Spell Attack: +6 to hit, reach 5 ft., one creature. Hit: 13 (2d8 + 4) necrotic damage, and the target must succeed on a DC 14 Constitution saving throw or its hp maximum is reduced by an amount equal to the damage taken. This reduction lasts until the creature finishes a long rest after drinking 1 pint of water. The target dies if this effect reduces its hp maximum to 0.
