You have resistance to fire damage and a bonus to Dexterity saving throws against spells that deal fire damage while the shield is equipped.

In addition, if you are targeted by a mind-altering spell of 5th level or lower, you may use your reaction to have the shield absorb the spell.
The shield regains this ability the next day at dawn.

Shields require the Utilize action to Don or Doff. You gain the Armor Class benefit of a Shield only if you have training with it.

Notes: Resistance: Fire, Bonus: Dexterity Saving Throws
