Fang Dagger (Magic Dagger)

This sort of dagger is rare indeed in the North, but it is a favored weapon of evil thieves and wizards in Thay and in places to the south and east (the lands of Murghom, Semphar, Raurin, and Durpar). When sheathed, a fang dagger appears as a normal weapon. When drawn, it becomes a small, coiling emerald-green snake head and torso up to 6 inches long.
This “blade” has no cutting edge and cannot be used to sever ropes, parry other weapons, or the like. Its use does not alter the wielder's THAC0. A successful attack does only 1 hp piercing damage, but the struck victim must save against poison or suffer the snake's venom effect. A being who successfully saves against the poison of a fang dagger is forever immune to the poison of that particular dagger.
The poison effects of a fang dagger vary with the type of snake used, and may be of injected types A, B, C, D, E, F, or O (see Table 51 in the DMG), The venom is never exhausted, no matter how often the blade is used, unless the blade's head is destroyed. The snake head is itself AC 6 and is destroyed if it suffers more than four hp damage in a round. It makes all saving throws as a 1HD monster.
The making of such a blade requires a live snake (of the poison type desired), an intact dagger, and a secret ritual involving the powdering of gems, the casting of a temporal stasis spell, and the use of a drop of sovereign glue.
