From D&D Wiki
Medium undead, chaotic evil
Saving Throws Wis +2, Cha +6
Spellcasting. The ghastly warlock is a 4th level spellcaster. Its spellcasting ability is Charisma (spell save DC 14, +6 to hit with spell attacks). The ghastly warlock has 3 spell slots, and can expend a spell slot to cast any spell it knows. The ghastly warlock knows the following warlock spells:
Eldritch Blast. Ranged Spell Attack: +6 to hit, range 120 ft., one or two targets. Hit: 11 (2d10) force damage if the ghastly warlock attacked one target, or 5 (1d10) force damage if the ghastly warlock attacked two.
Iron Rod. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 4) bludgeoning damage and 4 (1d8) necrotic damage. If the target is a creature other than an undead, it must succeed on a DC 12 Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
A crafty ghoul who has made a pact with a fiend.
