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 white dragon's draught produces a 30-foot cone dealing 6d6 cold damage with a reflex save DC of 23.

Prerequisites: Craft Wondrous Item, dragon type or dragonblood subtype.
Cost to Create: 500 gp (plus 200 gp for base item), 40 XP, 1 day.
