Mal brought the magic back to Hades’ ember by restoring it after Celia had ruined it with water, and then Uma used her necklace’s power to reawaken the ember so Mal could defeat Audrey. In other words, Mal didn’t create the magic from scratch — she got it back through Hades’ ember, then used that renewed power in the final battle.

What happened

  • Hades’ ember is the key magical item tied to Hades’ power.
  • Celia dunked it in water, which made it useless.
  • Later, Uma’s necklace restored the ember’s magic.
  • That let Mal tap into its power and beat Audrey.

Why it mattered

Mal needed the ember because Audrey’s curse and power were overwhelming Auradon, and the ember gave Mal the boost she needed to turn the fight around. The story frames it as a turning point where Mal accepts a bigger, more complicated kind of power instead of just relying on her own magic.

TL;DR

Hades’ ember lost its power in water, then Uma restored it, and Mal used that returned magic to defeat Audrey and move the story toward the barrier coming down.
