Korasi's Sword is a rare/uncommon drop from Yew, and Magic bots, along with Kalphites, and Kalphite Marauders.
The sword has +12 attack damage, but a low durability of 100. When a target is attacked, a lightning bolt is called down on the target, and the victim takes damage, and is ignited and struck by the lightning simultaneously.
- Being a high damage weapon with a level requirement of only 15, this sword can be great for beginners when high damage is needed.
- Enchanting the sword with Unbreaking 3 can increase the longevity of the weapon. Additionally if multiple swords are in one's posession, the repair cost of combining the swords on an anvil are cheap.
