Baelnorn Lich

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

Unusual Nature. The lich doesn’t require air, food, drink, or sleep. Magic can’t put it to sleep.

Multiattack. The lich makes two Radiant Strike attacks.

Radiant Strike. Melee or Ranged Spell Attack: +9 to hit (the target gains no benefit from less than total cover), reach 5 ft. or range 60 ft., one target. Hit: 15 (3d6 + 5) radiant damage.

Healing Touch (3/Day). The lich touches another creature. The target magically regains 18 (3d8 + 5) hit points and is freed from one curse afflicting it (lich’s choice).

Holy Fire (3/Day). The lich chooses a point it can see within 60 feet of it. Each creature in a 10-foot-radius, 40-foot-high cylinder centered on that point must make a DC 17 Dexterity saving throw. A creature takes 14 (4d6) fire damage and 17 (5d6) radiant damage on a failed save, or half as much damage on a successful one.

Spellcasting. The Lich casts one of the following spells as an action, ignoring the normal casting time, and using Wisdom as the spellcasting ability (spell save DC 17, +9 to hit with spell attacks):

at will: guidance, mending, spare the dying, thaumaturgy

1/day each: bless, command, create or destroy water, augury, calm emotions, hold person, daylight, dispel magic, banishment, divination, dispel evil and good, scrying

The lich can take 2 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 lich regains spent legendary actions at the start of its turn.

Attack. The lich makes one attack with its Radiant Strike.

Shimmering Aura (Costs 2 Actions). Until the end of the lich’s next turn, it sheds bright light in a 30-foot radius and dim light for an additional 30 feet. Any creature that starts its turn in the bright light must succeed on a DC 17 Constitution saving throw or be blinded until the end of the lich’s next turn. If the bright light overlaps with an area of darkness created by a spell of 3rd level or lower, the spell that created that darkness is dispelled.
