This armor shimmers with a variety of hues, and it feels slick to the touch.

A suit of armor that has this property grants resistance 10 against all energy attacks (acid, cold, electricity, fire, and sonic). When you are the subject of an energy attack, the armor also radiates light for a number of rounds equal to the points of damage absorbed (to a maximum of 10 rounds). This light is sufficient to brightly illuminate a 30-foot-radius area and casts shadowy illumination in a 60-foot-radius area.
If the armor absorbs more energy damage while it is radiating light, the first effect overlaps (does not stack with) the effect that was already in place. For example, if the armor absorbs 4 points of damage from one attack and another 6 points from an attack 2 rounds later, it radiates light for a total of 8 consecutive rounds (4 –2 + 6). Likewise, if the armor absorbs 10 points from one attack and another 5 points from an attack 2 rounds later, it radiates light for 10 consecutive rounds (because 8 rounds remain from the earlier effect, continuing past the end of the second effect’s 5 rounds).
