Adamantine Breastplate of the Everforge

This breastplate is made of adamantine, one of the hardest substances in existence. It was forged by dwarves in the Everforge, a magical forge channeling elemental fire. While you're wearing it, any critical hit against you becomes a normal hit and you gain a +1 bonus to your armor class.

In addition, you can cast the Light cantrip at will, but the light emanates from the breastplate.

This armor consists of a fitted metal chest piece worn with supple leather. Although it leaves the legs and arms relatively unprotected, this armor provides good protection for the wearer's vital organs while leaving the wearer relatively unencumbered.
