The dragon halberd is a halberd that requires 60 Attack and completion of Regicide to wield. Like all halberds, the dragon halberd has the ability to attack from two squares away, and thus the only dragon melee weapon usable for safespotting. It can be purchased from the Quartermaster at Tyras Camp for 325,000 coins, but can be bought from the Grand Exchange or another player for a substantially lower price.
The weapon's extra square of reach and high offensive bonuses make it useful for fighting certain large monsters from safe spots. Its downsides include the quest requirement to wield it, the fact that it is a two-handed weapon (and thus cannot be wielded with a shield or off-hand weapon) and its slow attack speed.
The dragon halberds special attack makes it a fantastic choice of weapon when fighting lots of enemies in a confined space such as the abyss, especially when used in conjunction with other abilities such as cleave, hurricane and quake.
The dragon halberd has a special attack called Sweep, which swipes all the targets in front of the player (similar to Cleave, but with a larger area) twice, and the area doesn't seem to be affected by whether an opponent 1 or 2 squares away is targeted. When using the special attack the ability Cleave has to be off cool-down for the player to use the special attack.This however does not put the ability Cleave on cool-down. The special attack uses 30% adrenaline.
Unlike before the Evolution of Combat, the size of the opponent does not matter.
Before the Evolution of Combat, this weapon's special attack was a wide slash with increased strength that hit multiple enemies if they were lined up correctly (in a multi-combat zone) and would hit larger monsters twice.
The dragon halberd has the exact same stats and same style as a dragon 2h sword and Balmung but has an extra square of reach, making the dragon halberd always superior to those with the requirements, unless one is fighting dagannoths.
