Thunder Shield

The Thunder Shield is a shield-type weapon with a lower damage reduction on block than most other shields which deals electric DPS when held up or in a radius around the player after a successful parry. Reusing the shield while it's charged will discharge the energy, dealing shock damage and stunning nearby enemies.

Trivia

 * Thunder Shield worked differently prior to v1.3. It wasn't able to deal area damage or discharge the energy, but successful parries increased the DPS by ~2.7 times.
