Lich

If the monster fails a saving throw, it can choose to succeed instead.

If destroyed, the monster reforms in days if it has a spirit jar, reviving with all its Hit Points. The new body appears in an unoccupied space within the monster's lair.

The monster makes three attacks, using or in any combination.

The monster casts one of the following spells, using Intelligence as the spellcasting ability (spell save DC ):
At Will: Detect Magic, Detect Thoughts, Dispel Magic, Fireball (level 5 version), Invisibility, Lightning Bolt (level 5 version), Mage Hand, Prestidigitation
2/Day Each: Animate Dead, Dimension Door, Plane Shift
1/Day Each: Chain Lightning, Finger of Death, Power Word Kill, Scrying

. .

. , and the target has the Paralyzed condition until the start of the monster's next turn.

The monster casts Counterspell or Shield in response to the spell's trigger, using the same spellcasting ability as Spellcasting.
