These thin, interlocking rings are made of different metals, including silver, adamantine, mithral, and platinum.

A ring of master artifice functions only if you can imbue infusions (see the EBERRON Campaign Setting). Assembling the ring from its various components requires 5 minutes and a successful DC 22 Intelligence check, which you can attempt any number of times. Once assembled, a ring of master artifice must be worn for 24 hours for its magic to take effect. After that time, you gain the ring’s benefit every time you concentrate to regain your daily allotment of infusions.
The ring increases the number of infusions you can imbue daily. A ring of master artifice provides one bonus 3rd-level infusion and one bonus 4th-level infusion.
