Ring of Adaptation

A ring of adaptation normally appears as a simple gold band with no markings of any kind. The band itself is wide, taking up almost all the space between the knuckle and first finger joint. The ring resizes itself to this proportion to match the finger length of its wearer. Powers: In its base state, a ring of adaptation has no apparent powers. When the wearer takes damage from an energy attack form, however, it blazes to life. When the wearer takes damage from fire, cold, electricity or acid, the ring changes to a new shape and appearance: a burning wheel of fire, a band of solid ice, a crackling arc of lightning, or a bubbling green ring of swirling acid. None of these actually harm the wearer or anyone else touching the transformed item, of course. While in its transformed state, the ring of adaptation provides 20 points of resistance against the energy type that matches its new form. Thus, for example, a flaming ring provides fire resistance 20. This resistance does not apply to the damage the wearer just took, only to future attacks. The ring remains in its transformed state for 10 minutes before reverting to a neutral form. A ring of adaptation can adapt to only one attack type at a time. If a different attack type strikes the wearer before it reverts, the ring changes form to match the new type. Short of blasting the wearer with a specific energy attack, there is no way to make the ring change on demand.
