Charm of Cozmioko's Glory

This charm infuses you with the righteous vengeance of the brass dragon Cozmioko. You can use it as a Magic action and choose one of the following effects:

• Cozmioko's Fire.

  You cast the Wall Of Fire spell (level 7 version, spell save DC 20), requiring no spell components.

• Cozmioko's Light.

  You regain 28 (8d6) Hit Points.

• Cozmioko's Revenge.

  One Melee weapon you are holding is infused with supernatural might for 1 minute or until you aren't holding the weapon. Once per turn, when you hit a Dragon with this weapon, the Dragon takes an extra 3d6 damage of the weapon's type.

Once you use the charm, it vanishes from you.
