Multiattack

A quickstep makes two attacks with its moonlight rapier and one with its hidden dagger.

Moonlight Rapier

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) piercing damage plus 7 (2d6) cold damage.

Hidden Dagger

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 6 (1d4 + 4) piercing damage plus 3 (1d6) cold damage.

Freezing Steel (Recharge 6)

Each creature within 10 feet of the quickstep must make a DC 15 Constitution saving throw as the quickstep whirls in a blur of cold steel. On a failure, a target takes 9 (2d8) piercing damage and 7 (2d6) cold damage and is paralyzed for 1 round. On a success, a target takes half the piercing and cold damage and isn't paralyzed.
