Life Drain. The Atropal targets one creature it can see within 120 feet of it. The target must succeed on a DC 24 Constitution saving throw, taking 36 (8d8) necrotic damage on a failed save, or half as much damage on a successful one. The Atropal regains a number of hit points equal to half the amount of damage dealt. The targets hit point maximum is also reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.

Summon Wraith (Recharge 6). The Atropal summons 1d4+1 Wraiths which materializes within 60 feet of it in an unoccupied space it can see. The wraith obeys its summoner's commands and can't be controlled by any other creature. The Wraith vanishes when it drops to 0 hit points or when its summoner dies.

Wail of Enfeeblement. (Recharge 4-6). The Atropal lets out a withering wail. Any creature within 60 feet of the Atropal that can hear the wail must succeed on a DC 24 Constitution saving throw or the target's Charisma, Intelligence and Wisdom score is reduced by 1d4. The target dies if this reduces any of it's ability scores to 0. Otherwise, the reduction lasts until the target finishes a short or long rest.

Spell Reflection. If the Atropal makes a successful saving throw against a spell by means other than using it's legendary resistance, or if a spell attack misses it, the Atropal can choose another creature (including the spellcaster) it can see within 120 feet of it. The spell targets the chosen creature instead of the Atropal. If the spell forced a saving throw, the chosen creature makes its own save. If the spell was an attack, the attack roll is re-rolled against the chosen creature.

The Atropal can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The Atropal regains spent legendary actions at the start of its turn.
