Wondrous Item

Legendary Requires Attunement

Stormgirdle is a wide belt made of thick leather branded with the symbol of Stronmaus, the Storm Lord. The girdle's clasps are made from dragon ivory.   Dormant. While wearing the Stormgirdle in its dormant state, you have resistance to lightning damage and thunder damage, and your Strength score becomes 21 if it isn't already 21 or higher. In addition, you can use an action to become a Storm Avatar for 1 minute, gaining the following benefits for the duration:

• You have immunity to lightning damage and thunder damage.
• When you hit with a weapon attack that normally deals bludgeoning damage, it deals thunder damage instead. When you hit with a weapon attack that normally deals piercing or slashing damage, it deals lightning damage instead.
• As a bonus action, you can choose one creature you can see within 30 feet of you to be struck by lightning. The target must make a DC 15 Dexterity saving throw, taking 3d6 lightning damage on a failed save, or half as much damage on a successful one.

Once you use the girdle's Storm Avatar property, that property can't be used again until the next dawn.
