Dart of the hornets' nest

A dart of the hornets' nest, or a dart of the hornet's nest,     was an extremely powerful thrown weapon.

Description
In terms of appearance, these magical darts appeared the same as ordinary darts. However, when thrown, the darts would multiply. The multiplied darts would then emit mad buzzing sounds, similar to that of hornets. Such a powerful weapon came at a very high cost, as a single dart cost approximately 7,500 gp.

Powers
Right after being launched, the dart would multiply and zoom towards the intended target. Generally, the more darts that were summoned, the lower chance they had of hitting. Up to twenty darts could be generated, causing an extraordinary amount of damage if the majority of them hit.

History
In the 14 century DR, a few organizations utilized these powerful darts. The Black Circle that had overtaken New Verdigris stored one of these darts in a highly guarded armory, as did the Silver Blades. A single dart of the hornet's nest was stashed in a black dragon lair in Dragons' Aerie, as well as on the second level of the Mages' Guild of Myth Drannor. The River's Heart magic shop of Neverwinter had a dart of the hornet's nest available for purchase, but it was very expensive.

The adventurer by the name of Torm often carried many magical items, sometimes including a dart of the hornets' nest.
