Until this grapple ends, the target is restrained, the medusa can automatically hit the target with its tail, and the medusa can't make tail attacks against other targets.   Shortsword. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 9 (2d6 + 4) piercing damage plus 7 (2d6) poison damage.   Longbow. Ranged Weapon Attack: +5 to hit, range 150/600 ft., one target. Hit: 10 (2d8 + 2) piercing damage plus 7 (2d6) poison damage.   Bonus Action - Throw. If holding a grappled creature. the medusa can throw the creature at a target. Range 20ft, target must succeed a Dex saving throw DC 14 or take 3d8 bludgeoning damage. Thrown creature automatically takes 3d8 damage regardless of save result.   Bonus Action - Tail Swipe. All medium or smaller creatures adjacent to the medusa must make a DC 16 Dex saving throw or be knocked prone. They also suffer 9 (2d6 + 4) bludgeoning damage or half as much on a success.

Reactions

Shove. The medusa adds 5 to its AC against one melee attack that would hit it. To do so, the medusa must not be grappling a creature with its tail. The attacking creature must also make a DC 16 Strength Saving throw or be pushed 10 feet back.
