Several interlocking rings of many different metals—including adamantine, gold, and mithral—seem to thrum faintly with power.

A greater 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 greater 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 greater ring of master artifice provides one bonus 5th-level infusion and one bonus 6th-level infusion.
