Ring of Forcefangs
Aura moderate evocation; CL 9th
Slot ring; Price 8,000 gp; Weight
This band negates any force spell or spell-like ability targeted at the wearer. Doing so gives the ring a number of charges equal to the spell level of the incoming force effect. The ring can hold a maximum of nine charges. If an incoming force attack would charge the ring beyond this limit, the ring does not negate the attack or gain charges, and the attack affects the wearer normally. On command, the wearer can use the ring's charges to cast magic missile, unleashing one missile (1d4+1 force damage) per charge but no more than five missiles per round.
Requirements Forge Ring, Heighten Spell, magic missile; Cost 4,000 gp
