Corrupt Vesta's longsword
From Emps-World Wiki
Corrupt Vesta's longsword is a strong ancient weapon obtained as a rare drop from the Spectral tender. Unlike the uncorrupted version it does not have a special attack. It requires 20 Attack and 78 Strength to equip.
Once used in combat a Corrupt Vesta's longsword is no longer tradeable and can only be repaired by using Ancient energy on it. Recharging them to full with the ancient energy will not make them tradable again. After dealing damage with the longsword 3000 times, it will crumbles into dust if not recharged in time.
