Spiral Heart (スパイラルハート supairaru hāto) is an attack performed by Amu Hinamori as Amulet Heart. She performs it by spinning her Heart Rod and throwing it. When she misses her target, it comes back to the target's area like a boomerang.
It also has the power to sprinkle paralyzing dust around its target to make sure they don't get away when she purifies them.
- Its powered-up counterpart in the anime is "Spiral Heart Special".
