Legendary Resistance (3/Day). The lichs body or vestments are warded with three protective runes. When the lich fails a saving throw, it can choose to succeed instead. When it does so, one of its protective runes disappears.

Rejuvenation. If it has a soul vessel, a destroyed lich gains a new body in 1d10 days, regaining all its hit points. The new body forms within 10 feet of the soul vessel.

Tongueless Utterance. Unless a spell has only a vocal component, the lich can cast the spell without providing a vocal component.

Turn Resistance. The lich has advantage on saving throws against any effect that turns undead.

Undead Nature. A lich doesnt require air, sustenance, or sleep.

Thunderwave (1st-Level; S). Thunder rolls from the lich in a 15-foot cube. Each creature in the area makes a DC 20 Constitution saving throw. On a failure a creature takes 9 (2d8) thunder damage and is pushed 10 feet from the lich. On a success a creature takes half damage and is not pushed.

Blur (2nd-Level; V, Concentration). The lichs form is blurred. Attack rolls against it are made with disadvantage unless the attacker has senses that allow them to perceive without sight or to see through illusions (like blindsight or truesight).

Fireball (3rd-Level; S, M). Fire streaks from the lich to a point within 120 feet and explodes in a 20-foot radius spreading around corners. Each creature in the area makes a DC 20 Dexterity saving throw taking 21 (6d6) fire damage on a failed save or half damage on a success.

Confusion (4th-Level; S, M, Concentration). Each creature within 10 feet of a point the lich can see within 120 feet makes a DC 20 Wisdom saving throw becoming rattled until the end of its next turn on a success. On a failure a creature is confused for 1 minute and can repeat the saving throw at the end of each of its turns ending the effect on itself on a success.

Disintegrate (6th-Level; S, M). The lich disintegrates a target within 60 feet. A Large or smaller nonmagical object or creation of magical force or a 10-foot-cube section thereof is automatically destroyed. A creature makes a DC 20 Dexterity saving throw taking 75 (10d6 + 40) force damage on a failed save. If reduced to 0 hit points the creature and its nonmagical gear are disintegrated and the creature can be restored to life only with true resurrection or wish.

Eldritch Aura. The lich surrounds itself with a magical, rune-covered, glowing, translucent aura in a 10-foot radius. The aura moves with the lich and casts dim light inside its area. The aura disappears at the beginning of the lichs next turn.

Death Aura. The aura casts purple light. Each living creature that ends its turn inside the aura takes 17 (5d6) necrotic damage, and the lich regains the same number of hit points.

Shield Aura. The aura casts orange light. It has 35 hit points. Whenever the lich would take damage, the aura takes the damage instead, and the aura visibly weakens. If the damage reduces the aura to 0 hit points, the aura disappears, and the lich takes any excess damage.

Spell Shield Aura. The aura casts blue light. Any spell cast with a 5th-level or lower spell slot from outside the aura can't affect anything inside the aura. Using a spell to target something inside the aura or include the auras space in an area has no effect on anything inside.

Sabotage Spell. When a creature within 60 feet casts a spell that targets the lich, the lich attempts to interrupt it. The lich makes an Intelligence check against a DC of 10 + the spells level. On a success, the spell fails, and the caster takes 10 (3d6) necrotic damage.
