Jewel of Force Resistance

Wondrous item, rare (requires attunement)

This perfectly spherical, iridescent gem glows with a soft, pulsing light. Elite Kigum guardians often wear these jewels set into heavy amulets or embedded in their armor.

Properties

While attuned to this jewel, you have resistance to force damage.

Kinetic Absorption: As a reaction when you take force or bludgeoning damage, you can absorb some of the kinetic energy. You gain immunity to the triggering damage, and the jewel gains a charge. The jewel can hold up to 3 charges. You can use an action to expend 1 to 3 charges to release the energy as a shockwave. Each creature within 15 feet of you must make a DC 15 Strength saving throw, taking 2d8 force damage per charge expended and being pushed 10 feet away on a failed save, or half as much damage and not pushed on a successful one.

Once the kinetic absorption reaction has been used, it can't be used again until the next dawn.
