Desalinate

Desalinate removes dissolved salts and other contaminants from seawater. The filtered water is potable. This spell is not like create water, which creates something from nothing, and desalinate is much less effective than the priest spell purity food and drink. However, it will work, in a pinch. Desalinate simply separates the desirable portion of the seawater (water) from the undesirable materials (dissolved salts and minerals). Desalinate has no effect on living creatures.

The material component (consumed) is a small piece of fine paper or cloth (worth 1 gp) which is used as a filter.
