 ***Immortal Nature.*** Sul Khatesh doesn't require air, food, drink or sleep. She also can't die permanently. Upon her death, she reforms elsewhere in the multiverse and becomes active again at a time set by the DM.
***Innate Spellcasting.*** Sul Khatesh's spellcasting ability is Intelligence (spell save DC 26, +18 to hit with spell attacks). She can innately cast the following spells, requiring no material components:
*At will:* Counterspell, Detect Magic, Detect Thoughts, Dispel Magic, Eyebite, Fireball, Lightning Bolt, Shield
*3/day each:* Chain Lightning, Create Undead, Dream, Hold Monster, Mass Suggestion, Scrying
*1/day each:* Foresight, Gate, Power Word Kill, Teleport
***Legendary Resistance (3/Day).*** If Sul Khatesh fails a saving throw, she can choose to succeed instead.
***Magic Resistance.*** Sul Khatesh has advantage on saving throws against spells and other magical effects.
 ***Multiattack.*** Sul Khatesh makes four attacks with Arcane Blast.
***Arcane Blast.** Ranged Spell Attack:* +18 to hit, range 120 ft., one target. *Hit:* 15 (1d10 + 10) force damage.
***Magic Staff.** Melee Weapon Attack:* +12 to hit, reach 5 ft., one target. *Hit:* 36 (5d12 + 4) force damage.
***Arcane Cataclysm (Recharges after a Long Rest).*** Sul Khatesh conjures orbs of magical energy that plummet to the ground at three different points she can see within 1 mile of her. Each creature in a 40-foot-radius sphere centered on each point must make a DC 26 Dexterity saving throw, taking 71 (11d12) force damage on a failed save or half as much damage on a successful one. A creature in the area of more than one arcane burst is affected only once. The area of each arcane burst then acts as an Antimagic Field for 1 hour. Sul Khatesh and spells she casts are unaffected by these fields.
***Change Shape.*** Sul Khatesh magically polymorphs into a humanoid, beast, or giant that has a challenge rating no higher than her own, or back into her true form. She reverts to her true form if she dies. Any equipment she is wearing or carrying is absorbed or borne by the new form (her choice).
 Sul Khatesh can take 3 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature's turn. Sul Khatesh regains spent legendary actions at the start of its turn.
**Attack.** Sul Khatesh makes two attacks with her Arcane Blast or one attack with her magic staff.
**Consume Magic (Costs 2 Actions).** Sul Khatesh targets a creature within 120 feet of her who is concentrating on a spell. The target must succeed on a DC 26 Constitution saving throw or its concentration is broken on the spell, and Sul Khatesh gains 5 temporary hit points per level of that spell.
**Maddening Secrets (Costs 3 Actions).** Sul Khatesh whispers an arcane secret into the mind of a creature she can see within 60 feet of her. The target must succeed on a DC 26 Wisdom saving throw or expend one of its spell slots of 3rd level or lower and deal 26 (4d12) force damage to each creature within 30 feet of it. A creature that fails the saving throw but can't expend a spell slot is instead stunned until the end of its next turn.
