The Thunder Shield is a shieldweapon which has a lower damage reduction on block than most other shields and 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. This item is exclusive to the Rise of the Giant DLC.
Details
Base Absorbed Damage: 50%
Special Effects:
Parrying charges the player up, dealing 32 base electric DPS in an area of effect.
Keeping the shield up also deals the same electric DPS to any enemy in front of the player.
Using the shield again when charged up discharges instantly, dealing 32 base shock DPS for 2 seconds and stunning nearby enemies.
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.
