Normally stored in the form of small, salty pellets in a dry container, this reagent can be mixed with a flask of water and stored safely.

Nushadir neutralizes acid; a vial of pellets or a flask of nushadir-water is enough to render a cubic foot of acid safe to touch in 1 minute, though this is usually too slow to prevent damage from a thrown vial of acid or the contents of a large monster’s gullet. Nushadir vapors are slightly irritating to the eyes, nose, and mouth, causing nausea for 1d4 rounds after close exposure (Fortitude DC 10 negates).
