The dragon scimitar has a special attack called Sever which prevents the target from using protection prayers for 5 seconds. The attack also has a higher chance of hitting the target. The special attack requires 55% adrenaline. It should be noted that the special attack will not disable monster protection prayers, and therefore is significantly less useful in PvM and training scenarios compared to other dragon weapons.
The off-hand dragon scimitar does not have a special attack.
The dragon scimitar was not actually released until almost four months after the Monkey Madness quest, on 29 March2005. Six days later on 4 April, it was announced that the special attack of the dragon scimitar was not working as intended and could not be fixed. It was changed to the old special attack on that day.
On 23 July2009, five days before the scheduled update, the dragon scimitar image in the Grand Exchange Database was replaced by the new model. Players found the image and posted about it in the RuneScape Forums, making it widely known before Jagex removed the image a few hours later. Five days later, the image was once again put up along with the official release.
On 10 August2009, an update enlarged the blade of the dragon scimitar and gave it a more red-plastic colour and a metallic luster effect.
On 15 June2010, an update enabled players that had completed Monkey Madness to buy dragon scimitars from Dealga in the Varrock Sword Shop for 100,000 coins.
If the player asked Zeke to sell them a Dragon scimitar, he would say,"Seriously, you'll be a monkey's uncle before you'll ever hold a dragon scimitar." In the Monkey Madness quest (the quest a player must complete to wield a dragon scimitar), players have to play the role of a monkey's uncle to complete a certain part of the quest.
