Animated Grand Piano

Antimagic Susceptibility. The piano is incapacitated while in the area of an antimagic field. If targeted by dispel magic, the piano must succeed on a Constitution saving throw against the caster's spell save DC or fall unconscious for 1 minute. While under this affect, the piano is usable as a perfectly tuned musical instrument.

False Appearance. While the piano remains motionless, it is indistinguishable from a normal piano.

Inspire (3/Day). The piano can use a bonus action to play a quick tune to inspire an ally. Using a bonus action, the piano targets a creature within 30 feet of it. The target gains 1d8 inspiration die that the target can add to an attack roll, ability check or saving throw. The target can use this die after the roll is made, but before the outcome is determined.

Multiattack. The piano makes two slam attacks

Slam. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 17 (2d12 + 4) Bludgeoning damage.

Cutting Tune (3/Day). The piano can attempt to distract an enemy by slamming on its keys; conjuring a shrill, discordant sound. When a creature within 60 feet of the piano makes an attack, the piano can use a reaction to roll 1d8 and subtract the number from the attack roll. This ability can be used after the roll is made, but before the DM determines whether the attack roll succeeds or fails.
