Multiattack

The marilith makes two Dagger attacks, two Mace attacks, and two Longsword attacks. It can replace two Dagger attacks with a Tail attack.

Mace

_Melee Weapon Attack:_ +9 to hit, reach 5 ft., one target. _Hit:_ 11 (2d6+4) bludgeoning damage plus 7 (2d6) fire damage.

Longsword

_Melee Weapon Attack:_ +9 to hit, reach 5 ft., one target. _Hit:_ 13 (2d8+4) slashing damage plus 7 (2d6) fire damage.

Tail

_Melee Weapon Attack:_ +9 to hit, reach 10 ft., one creature. _Hit:_ 20 (3d10+4) bludgeoning damage plus 7 (2d6) fire damage. If the target is Medium or smaller, it is grappled (escape DC 17). Until this grapple ends, the target is restrained, the marilith can automatically hit the target with its Tail, and the marilith can't make Tail attacks against other targets.
