Ring of the Forcewall

This ring is carved from clear quartz and is engraved with complex magic sigils.

A ring of the forcewall creates a small, nigh-impenetrable barrier. This ring has 3 charges, which are renewed each day at dawn. Spending 1 or more charges creates a 10-foot-square vertical wall of force (as the spell) up to 30 feet away from you. The number of charges spent determines the duration of the wall.

1 charge: 2 rounds.

2 charges: 3 rounds.

3 charges: 4 rounds.

Prerequisites: Forge Ring, wall of force.

Cost to Create: 2,550 gp, 204 XP, 6 days.
