Ring of Thunderclaps

This ring is carved from a single piece of lapis lazuli and has a lightning bolt etched along its rim.

You can activate this ring as a swift (command) action to make a melee touch attack before the end of your turn that deals 1d8+5 points of electricity damage if successful. This ability functions three times per day.

Once per day, upon successfully using the ring to damage a target, you can activate a second ability of the ring as a free (command) action to create a powerful thunderclap that mimics a shout spell.

Prerequisites: Forge Ring, shocking grasp, shout.

Cost to Create: 3,000 gp, 240 XP, 6 days.
