Function#
The Mask of Aging gave its wearer the ability to slightly accelerate the life processes of one or more targets, leaving them slower and weaker. The qualifier "slightly" applied throughout. The mask did not destroy targets outright; it advanced their decline by a degree sufficient to reduce combat effectiveness but did not function as an instant-kill power.
The mask's second clause extended the effect to non-living and inorganic matter. A wielder could rust armor, decay tools, and weaken structural materials. Applied to a sword mid-swing or to a load-bearing wall, the power could alter the outcome of an engagement without ever touching the opponent directly. This breadth, more than the rate of organic aging, accounted for the mask's reputation.
