So...
Breath Weapon (Su): A mustard dragon has two types of breath weapon, a cone of disease gas and a cone of blinding gas. Creatures within a cone of disease gas suffer Strength and Dexterity damage equal to half the age category of the dragon. A successful Fortitude(?) save halves the damage. A creature reduced to Strength 0 and Dexterity 0 dies. Creatures within a cone of blinding gas must succeed on a Fortitude save or be permanenty blinded, or dazzled for 1d6 rounds plus 1 round per age category of the dragon on a successful save.
I borrowed the duration from the silver dragon's paralyzing gas.
