The only way to acquire a Thunderstone is by completing the A Worthy Tribute stage of an Enclave Votive. This is a one-time-per-votive quest reward, not a repeatable farm — you receive it as a session item that persists only until logout. To maximise utility, complete an Enclave Votive that is close to a Bisulcam or an active Hark, the Collector descent so you can immediately deploy the Thunderstone before the session ends. If unused, it vanishes from inventory on logout — there is no carry-over, no banking, and no merchant resale.

A quest item used to destroy Ode'n Bisulcam units, sabotage a Collector during a Siege Besieged stage, or skip the Nimrod boss fight in Hark, the Collector. Acquired exclusively by completing the A Worthy Tribute stage of an Enclave Votive — a one-time-per-votive quest reward. The Thunderstone is a session-only item that persists until logout; it vanishes from inventory on disconnect with no carry-over, banking, or merchant resale. Plan to deploy it near a Bisulcam or active Collector descent before the session ends.
