Dragon's Teeth
So named for their ability to kill dragons, Dragons Teeth are effectively any dragon’s Achilles heel. As part of draconic tradition (and a secret to their longevity and strength), when a dragon comes of age, they lock their Soma away into vessels known as Dragon’s Teeth. These vessels always come in pairs, and almost always takes the form of some kind of weapon, though in some rare cases it may instead manifest as some other type of item or instrument. Naturally, these items are fiercely guarded—for as useful as they are when turned against a dragon’s foes, they are even more effective at slaying their own creator. Some dragons choose to keep their Teeth close to them at all times, while others seek to ensure they are never in the same place as the weapons designed to slay them. In either case, dragons are exceptionally careful about informing others as to the nature of their Teeth, and even more cautious in handing them away.
It is exceptionally difficult to destroy a Dragon’s Tooth. In the case where both of a dragon’s Teeth are successfully destroyed, that dragon faces Final Death.
