Lich

The lich can concentrate on two spells simultaneously. If it casts a third spell that requires concentration, the lich loses concentration on the oldest spell. If the lich is concentrating on two spells and loses concentration because of taking damage, it loses concentration only on the oldest spell.

If the lich fails a save, it can choose to succeed instead.

If it has a phylactery, a destroyed lich gains a new body in 1d10 days, regaining all its HP and becoming active again. The new body appears within 5 feet of the phylactery.

The lich has advantage on saves against any effect that turns undead.

The lich doesn't require air, food, drink, or sleep.

The lich is immune to poison damage, to exhaustion, and to the poisoned condition.

Melee or Ranged Spell Attack: +12 to hit, reach 5 ft. or range 120 ft., one target. Hit: 23 (4d8+5) force damage plus 17 (5d6) necrotic damage.

The lich uses Spellcasting.

Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 21 (4d8+3) bludgeoning damage plus 17 (5d6) necrotic damage, and the target must succeed on a DC 20 CON save or be paralyzed for 1 minute. The target can repeat the save at the end of each of its turns, ending the effect on itself on a success.

Each creature within 20 feet of the lich that isn't Undead must make a DC 20 CON save, taking 21 (6d6) necrotic damage on a failed save, or half as much damage on a successful one. The lich regains HP equal to the single highest amount of necrotic damage dealt.

The lich fixes its gaze on one creature it can see within 30 feet of it. The target must succeed on a DC 20 CHA save or be charmed or frightened (the lich's choice) until the end of its next turn.

The lich uses Lich's Gaze. It then makes four Arcane Death Burst attacks, or it makes three Arcane Death Burst attacks and one Death-Infused Rod attack. It can replace one attack with a use of Spellcasting.

The lich casts one of the following spells, using INT as the spellcasting ability (spell save DC 20).

• At Will: detect magic, disguise self, mage hand, message, prestidigitation
• 3/Day Each: charm, detect thoughts, dispel magic, invisibility (self only), mirror image
• 2/Day Each: bestow curse, cloudkill, dimension door, greater hold
• 1/Day Each: plane shift (self only), power word stun, wall of force

The lich can rise or descend vertically up to 20 feet and can remain suspended there. This bonus action works like the levitate spell, except there is no duration, and the lich doesn't need to concentrate to continue levitating each round.

When a creature the lich can see within 60 feet of it casts a spell, the lich can absorb the spell's energy, countering it. This works like the counterspell spell, except the lich must always make a spellcasting ability check, no matter the spell's circle. Its ability check for this is +12. If it successfully counters the spell, the lich gains 5 temporary HP for each level of the spell.

The lich uses Spellcasting.

Each creature within 20 feet of the lich that isn't Undead must make a DC 20 CON save, taking 21 (6d6) necrotic damage on a failed save, or half as much damage on a successful one. The lich regains HP equal to the single highest amount of necrotic damage dealt.

The lich moves up to its speed without provoking opportunity attacks. If the lich is levitating, it can use this legendary action to move horizontally, propelling itself with a blast of arcane power.
