Dark Sun Artifact: Bonesaw

 Bonesaw

Bonesaw is a magical shortsword, or gladius, created in the elemental plane of water. The sword has a hard wood handle, a single large tooth blade, with smaller, razor sharp, teeth connected to the sides of the main blade. It resembles a macuahuitl, but with sharp teeth instead of obsidian blades.
Bonesaw does not have any material penalties, for being made of bone.

Bonesaw is an intelligent weapon, with a loud and boisterous personality. It like insulting its wielding, it's favorite insult is calling the wielder a “freak” and variations of freak. It enjoys fighting and calls combat “Play time.” It also likes to talk about how great it is. In fact, Bonesaw just loves to talk, even at inappropriate times.
Bonesaw is Chaotic Neutral and has an Ego of 17. Bonesaw speaks the language of water elementals, Tyrian, Nibnese, and Balican.
Bonesaw's special purpose is to defeat the enemies of the elemental plane of water, which includes defilers, and silt, sun, and magma clerics. Bonesaw will not willingly attack a water cleric.

Suggested Means of Destruction
Leave Bonesaw on the Salt Flats for thirty days, with no shade or respite from the sun.
Leave Bonesaw in an active volcano for thirty days.
Leave Bonesaw at the bottom of the Silt Sea for thirty days.

Note: I took the idea for the weapon's obnoxious personality from Randy Savage's character Bonesaw McGraw in the 2002 Spider-Man film. So, I do my best impersonation of Savage when talking for the sword.
