Dragon dagger

The dragon dagger is the strongest dagger available, and can only be wielded by members who have at least 60 Attack and who have completed the Lost City quest.

Dragon daggers are prized for player killing because they are cheap, are frequently poisoned, and have a special attack which hits twice. High levels can hit over 60 with a single special, and due to the fact that the special only uses 25%, even a high level player could be dead in literally 5 seconds.

Note that a poisoned Dragon Dagger (ddp) sells for 30k-40k, a strong poisoned Dragon Dagger (ddp+ or dd+) sells for 40k-50k, and a super strong poisoned Dragon Dagger (dds, ddp++, or dd++) sells for 50k-60k.

As with all Dragon weapons, players cannot make this item using the Smithing skill. They can, however, be purchased in the Zanaris market place for 30,000 gp, from the traveling merchant standing by Baxtorian falls for 60,000 gp just west of Seers' Village and also at the dagger stall in Sophanem. Alternatively, a player with a high enough Hunting skill level can hunt magpie implings and hope to get a dragon dagger from them.
