A single dragon’s tooth servers as the stopper for this oversized flask. The liquid within bubbles turbulently with barely contained energy.

When a dragon or a creature that has the dragonblood subtype (see Races of the Dragon or Dragon Magic) consumes a dragon’s draught, it gains the ability to use a particular type of breath weapon once during the next hour as a standard action.
If you drink a second dragon’s draught before using the first, the effect of the first is lost.
Dragon’s draughts come in ten different varieties, one for each kind of true dragon.
This black dragon's draught produces a 80-foot line dealing 12d4 acid damage with a reflex save DC of 24.

Prerequisites: Craft Wondrous Item, dragon type or dragonblood subtype.
Cost to Create: 1,000 gp (plus 400 gp for base item), 80 XP, 2 days.
