Alghoul (5e Creature)
From D&D Wiki
Medium undead, chaotic evil
Pounce. If the alghoul moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 11 Strength saving throw or be knocked prone. If the target is prone, the alghoul can make one bite attack against it as a bonus action.
Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4 (1d6 + 1) piercing damage and the alghoul regains 3 (1d6) hit points.
Claw. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 6 (2d4 + 1) slashing damage.
Spines. Each creature within 5 feet of the alghoul must succeed on a DC 11 Dexterity saving throw or take 7 (2d6) piercing damage.
Alghouls, while can be found alone, many more can be found within packs of normal ghouls, leading them and using them to their advantage. They will generally try to have the normal ghouls distract you, while sneaking up behind and pouncing.
