The frostbite dagger is a weapon released with the Dungeoneering skill on 12 April2010. This weapon is dropped by icefiends and requires 36 Attack and 36 Magic to wield. When used on the Smuggler, he does not know what it could be used for. Its damage bonus lies between that of the kratonite and the fractite dagger.
When equipped with the flameburst defender, the frostbite dagger's maximum damage is decreased by 10, but the player receives +10% to their Attack.
Before the Evolution of Combat a player using a Frostbite 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 Frostbite dagger was wielded together with Flameburst defender.
