Avatar of Vol

Legendary Resistance (3/Day). If Vol fails a saving throw, she can choose to succeed instead.

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

Rejuvenation. Vol regenerates 20 hit points at the start of her turn.  Damage from fire or radiant energy sources is not regenerated.

Spellcasting. Vol is a 20th-level spellcaster. Her spellcasting ability is Intelligence (spell save DC 23, +15 to hit with spell attacks). Vol has the following wizard spells prepared:

Cantrips (at will): chill touch (see “Actions” below), fire bolt, mage hand, prestidigitation, ray of frost

1st level (4 slots): inflict wounds, shield, ray of sickness

Chill Touch (Cantrip). Ranged Spell Attack: +15 to hit, range 120 ft., one creature. Hit: 18 (4d8) necrotic damage, and the target can’t regain hit points until the start of the Avatar's next turn. If the target is undead, it also has disadvantage on attack rolls against the Avatar of Vol until the end of her next turn.

Paralyzing Claw. Melee Weapon Attack: +10 to hit, reach 5 ft., one creature. Hit: 13 (3d6 + 3) slashing damage plus 10 (3d6) cold damage, and the target must succeed on a DC 20 Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Poison Breath (Recharge 5–6). Illmarrow exhales poisonous gas in a 30-foot cone. Each creature in that area must make a DC 20 Constitution saving throw. On a failed save, a creature takes 35 (10d6) poison damage and is poisoned for 1 minute. While poisoned in this way, the creature can’t regain hit points. On a successful save, the creature takes half as much damage and isn’t poisoned.

A humanoid reduced to 0 hit points by this damage dies and rises at the start of Vol's next turn as a zombie. The zombie acts immediately after Vol in the initiative count and is permanently under her command, following her verbal orders.

Vol can take 1 legendary action. Only one legendary action option can be used at a time and only at the end of another creature’s turn. Vol regains spent legendary actions at the start of her turn.

Poison Breath (Costs 3 Actions). Vol recharges her Poison Breath and uses it.
