Avatar of Myrkul

Aura of Death’s Chill. Any non-undead creature that starts its turn within 20 feet of the Avatar takes 4 (1d8) cold damage and must succeed on a DC 14 Constitution saving throw or have its speed halved until the start of its next turn.

Multiattack. The Avatar makes two attacks, either two Soul-Reaping Scythe attacks or one Soul-Reaping Scythe and one Grave Bolt.

Soul-Reaping Scythe. The avatar sweeps its spectral scythe through a creature within 10 feet of it, dealing 23 (4d10+ 9) slashing damage DC 15 Constitution saving throw or have its point maximum is reduced by an amount equal to the necrotic 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.

Grave Bolt. Ranged Attack Roll: +7, range 60 ft. Hit: 11 (3d8 + 1) necrotic damage.

Grasp of the Grave (Recharge 5–6). Skeletal hands erupt from the ground in a 15-foot-radius area centered on a point the Avatar can see within 60 feet. Each creature in the area must succeed on a DC 14 Strength saving throw or become restrained until the end of its next turn. While restrained, a creature takes 7 (2d6) necrotic damage at the start of its turn.

Corpse Marionette (1/Turn). As a bonus action, the Avatar can animate the corpse of a Medium or Small humanoid it can see within 20 feet. The corpse rises as a Myrkul Servitor (use skeleton or zombie +10 hit points) and remains animated for 2 rounds, after which it collapses into inert remains.

The Avatar of Myrkul can take 2 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature’s turn.

Chill Step. The Avatar teleports up to 20 feet to an unoccupied space it can see. One creature within 5 feet of the destination takes 4 (1d8) cold damage.

Reap the Defiant (Costs 2 Actions). The Avatar targets one creature it can see within 30 feet that has 30 hit points or fewer. The target must succeed on a DC 15 Wisdom saving throw or immediately drop to 0 hit points.

When the Avatar is reduced to 63 hit points, it sheds a wave of pale necrotic energy. Each non-undead creature within 15 feet must succeed on a DC 14 Constitution saving throw or take 10 (3d6) necrotic damage (half on a success).
