Dust Of Acid Consumption

This brown dust is similar to dust of dryness, but affects acid rather than water and absorbs less liquid. If it is thrown into acid, a volume of as much as 10 gallons is instantly transformed into nothingness, and the dust becomes a marble sized pellet floating or resting where it was thrown. If this pellet is hurled, it breaks and releases the same volume of acid, dealing 1d6 points of acid damage per gallon absorbed into the pellet (maximum 4d6), affecting all creatures within a 30-foot radius of its point of impact. This is a splash weapon.

If the dust is used against an ooze that deals acid damage with its attacks, the creature must make a DC 18 Fortitude save or be destroyed. The dust deals 5d6 points of damage to the ooze even if its saving throw succeeds.
