Atropal - Avatar of Atropus

Anathematic Secrecy. The aspect can't be targeted by any divination magic or perceived through magical scrying sensors.

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

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

Negative Energy Aura. Creatures within 30 feet of the atropal can’t regain hit points, and any creature that starts its turn within 30 feet of the atropal takes 10 (3d6) necrotic damage.

If the atropal is struck by a vorpal sword, the wielder can cut the atropal’s umbilical cord instead of dealing damage. If its umbilical cord is cut, the atropal loses this feature.

Unyielding Essence. The atropal is immune to any spell or effect that would alter its form, as well as those that would read its thoughts, determine if it is lying, or magically influence its thoughts or behavior.

Turn Resistance Aura. The atropal and any other undead creature within 30 feet of it has advantage on saving throws against any effect that turns undead.

Necrotic Feast. Whenever the atropal is subjected to necrotic damage, it takes no damage and regains a number of hit points equal to the necrotic damage dealt.

Multiattack. The atropal makes two attacks, only one of which can be its Life Drain.

Touch. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 10 (3d6) necrotic damage. Any creature hit by this attack, except undead, must make a DC 15 Constitution saving throw. On a failure, that creature's Constitution score is decreased by (1d4). The target dies if this reduces its Constitution to 0. Otherwise, the reduction lasts until the target finishes a short or long rest.

Ray of Cold. Ranged Spell Attack: +12 to hit, range 120 ft., one target. Hit: 21 (6d6) cold damage.

Life Drain. The atropal targets one creature it can see within 120 feet of it. The target must succeed on a DC 19 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.

Summon Wraith (Recharge 6). The atropal summons a wraith, which materializes within 30 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.

Spell Reflection. If the atropal makes a successful saving throw against a spell, or a spell attack misses it, the atropal can choose another creature (including the spellcaster) it can see within 30 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 rerolled 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.

Touch. The atropal makes a touch attack.

Ray of Cold (Costs 2 Actions). The atropal uses its Ray of Cold.

Wail (Costs 3 Actions). The atropal lets out a withering wail. Any creature within 120 feet of the atropal that can hear the wail must succeed on a DC 19 Constitution saving throw or gain 1 level of exhaustion.
