Amulet of Sun's Warmth

This amulet feels warm to the touch, and when worn for more than 24 hours, grants the wearer Sun's Boon. 

Sun's Boon:  A soft glow permeates your skin and provides extra protection from harm in the form of 8 temporary hit points.

Once the temporary hit points provided by Sun's Boon are depleted, the amulet goes inert until another 24 hours pass.
