Rings of Giant Searing

Wondrous item, rare

These copper rings, one of which must be worn on each hand you have, grant a +1 bonus to the attack and damage rolls of your unarmed strikes.

When these rings are within 30 feet of a giant, they begin to glow with immense heat. Each time they heat, you suffer 2d6 points of fire damage. The rings remain heated for 10 minutes. During that time, your unarmed strikes deal an additional 1d6 points of fire damage.
