From D&D Wiki
Large fiend, chaotic evil
Damage Resistances bludgeoning, piercing, and slashing from nonmagical attacks
Multiattack. The screamer makes two attacks: one with its lamprey bite and one with its slashing fin.
Lamprey Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (1d10 + 4) piercing damage. If the screamer is larger than the target this attack deals an additional 11 (2d10) piercing damage.
Slashing Fin. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 13 (2d6 + 6) slashing damage.
Charge. The screamer flies up to 160 feet in a straight line, making one slashing fin attack against each creature that it passes through. Each target must succeed on a DC 15 Strength saving throw or be knocked prone. The screamer does not provoke opportunity attack during this movement.
Piercing Shriek (Recharge 5-6). The screamer unleashes an unholy shriek in a 30-foot cone, Each creature in that area must make a DC 14 Constitution saving throw. On a failed save, a creature takes 10 (3d6) psychic damage and is stunned until the end of its next turn. On a successful save, a creature takes half as much damage and isn't stunned.
Speeding blurs that leave shimmering trails of change-magics in the air behind them, screamers streak across the skies with a wailing cry. They slash foes they pass with razor-sharp horns and fins, before darting down to savage their chosen quarry with gnashing teeth.
