The hailstorm dagger is a weapon used in the Dungeoneering skill and requires 68 Attack and 68 Magic to wield. Its damage bonus lies between that of a gorgonite and promethium dagger, but it has lower accuracy. It is obtained as a drop from icefiends.
Former passive effect of the dagger alongside flameburst defender.
Before the Evolution of Combat, a player using a hailstorm dagger had a 20% chance of dealing an extra 50 magic-type damage with each hit. This passive effect damage was increased to 100 if hailstorm dagger was wielded together with flameburst defender.
