  • Inward Singing.

    Giga Rock starts inwards singing. Each creature within 60 feet must succeed on a DC 24 Strength saving throw or be pulled to within 15 feet in front of GIGA ROCK, take 1d10+10 necrotic damage, and GIGA ROCK regains 30HP. On a successful save, the creature isn't pulled and takes half damage.

    Crowd Surf. After resolving this ability, every Butt Rock Groupie may immediately move up to its speed toward Giga Rock or the nearest enemy without provoking opportunity attacks.

  • Swipe.

    (1d20+19) Giga Rock makes one Swipe attack against each creature of his choice within 60 feet. On a hit, the target takes 1d10+10 bludgeoning damage and Giga Rock chooses one:

    Push the target up to 30 feet.

    Knock the target prone.

    Grapple the target.

  • Dethchord.

    (CON 24) GIGA ROCK slams a devastating chord on his guitar. Each creature within line of sight takes 3d20+25 thunder damage, or half as much on a successful save.

    On a failed save, until the end of its next turn, the creature's speed is halved, it can't take reactions, and it can either take an action or a bonus action on its turn, not both.

At 310, GIGA Rock summons forth the dead. Enough butt rock groupie minions appear so that there are 4 for every PC and they attack the party at the start of the round

LAST STAND:

GIGA Rock is dying. 200 more damage until he dies. Until then he transforms to phase 2
