The volatile clay harpoon is one of the many possible tools that the Volatile clay tool can transform into. A difference from normal harpoons is that this one can be held in player's main hand slot like a barb-tail harpoon. This item can be stored in the Tackle box. Unlike other fishing equipment, only one volatile clay harpoon may be stored at a time.
The harpoon gives a 29,340 bonus experience in the fishing skill. Once the bonus experience is gained it is not necessary to carry the discharged tool around to benefit from it. The tool will lose 10% of its potential bonus experience if it is reverted. If players attempt to revert it once depleted, it will be destroyed.
