Ring of Brief Blessing

The clear crystal set into this silver ring glows faintly with a holy light.

A ring of brief blessing, which functions only if you are good-aligned, allows your attacks to pierce the defenses of evil foes. When you activate this ring, choose a single melee weapon you hold (or your unarmed strike). Until the end of your turn, that weapon is considered both magic and good-aligned for the purpose of overcoming the damage reduction of an evil creature, as well as for the purpose of affecting incorporeal evil creatures.

A ring of brief blessing functions once per day. Once it is activated, its glow fades. However, while wearing the ring you can expend a turn undead attempt as a standard (command) action to recharge it (which also restores its glow).

Prerequisites: Forge Ring, bless weapon.

Cost to Create: 500 gp, 40 XP, 1 day.
