Special Equipment. Kelek wears bracers of defense and carries a staff of striking with 10 charges. The staff regains 1d6 + 4 expended charges daily at dawn. If its last charge is expended, roll a d20; on a 1, the staff becomes a nonmagical quarterstaff.

Spellcasting. Kelek casts one of the following spells, using Charisma as the spellcasting ability (spell save DC 14):

At will: light, mage hand, prestidigitation

1/day each: dominate beast, fly, mirror image, web

Multiattack. Kelek makes three attacks using Sorcerer's Bolt, Staff of Striking, or a combination of them. He can replace one of the attacks with a use of Spellcasting.

Sorcerer's Bolt. Melee or Ranged Spell Attack: +6 to hit, reach 5 ft. or range 60 ft., one target. Hit:13 (2d12) force damage.

Staff of Striking. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit:8 (1d6 + 5) bludgeoning damage, or 9 (1d8 + 5) bludgeoning damage when used with two hands, and Kelek can expend up to 3 of the staff's charges, dealing an extra 3 (1d6) force damage for each expended charge.

Fiery Explosion (Recharge 4–6). Kelek creates a magical explosion of fire centered on a point he can see within 120 feet of him. Each creature in a 20-foot-radius sphere centered on that point must make a DC 14 Dexterity saving throw, taking 35 (10d6) fire damage on a failed save, or half as much damage on a successful one.

Arcane Defense (3/Day). When he is hit by an attack, Kelek protects himself with an invisible barrier of magical force. Until the end of his next turn, he gains a +5 bonus to AC, including against the triggering attack.
