The warlock is a 11th-level spellcaster. Its spellcasting ability is Charisma (spell save DC 14, +6 to hit with spell attacks). It regains its expended spell slots when it finishes a short or long rest. It knows the following warlock spells:
• Dagger: Melee or Ranged Weapon Attack: +3 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 4 (1d4+2) piercing damage.
• Misty Escape (Recharges after a Short or Long Rest): In response to taking damage, the warlock turns invisible and teleports up to 60 feet to an unoccupied space it can see. It remains invisible until the start of its next turn or until it attacks, makes a damage roll, or casts a spell.
