Warlock of Desirat

Eagle Telepathy. The warlock can magically command any eagle within 120 feet of it, using a limited telepathy.

Hellfire Magic. A creature that takes fire damage from the warlock becomes vulnerable to fire damage until the start of the warlock's next turn.

Innate Spellcasting. The warlock's innate spellcasting ability is Charisma (spell save DC 13, +5 to hit with spell attacks). It can innately cast the following spells, requiring no material components:

At will: eldritch blast, hellish rebuke (see "Actions" and "Reactions" below, respectively)

1/day each: darkness, fly, hex, mirror image, vampiric touch

Multiattack. The warlock makes two attacks with its Twilight Blade.

Twilight Blade. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 7 (1d10 + 2) slashing damage, plus 3 (1d6) fire damage.

Eldritch Blast (Cantrip). Ranged Spell Attack: +5 to hit, range 120 ft., one creature. Hit: 5 (1d10) force damage.

Hellish Rebuke. When the warlock is damaged by a creature it can see within 60 feet of it, it can use a reaction to force the creature to make a DC 13 Dexterity saving throw. The creature takes 11 (2d10) fire damage on a failed save, and half as much on a success.
