Dragon scimitar

The dragon scimitar is the strongest scimitar available, and can only be wielded by members who have at least 60 Attack and who have completed the Monkey Madness quest. It can be bought for 100,000 coins at Daga's Scimitar Smithy on Ape Atoll. The dragon scimitar has a special attack, Sever, which makes the player's attack more accurate and makes the target unable to use Prayer for 5 seconds, using 55% special attack energy.

As with all Dragon weapons, players cannot make this item using the Smithing skill.

This is arguably the second best weapon in the game, behind whip, and is used to train strength due to the whips inability to do that.
