Essential Water

Regular 
Like Create Water, but the water created is the magical essence of water. It extinguishes any type of fire in the same proportion that ordinary water extinguishes ordinary fire. It is also three times as thirst-quenching as ordinary water – in other words, a mere quart of Essential Water will keep someone hydrated for a full day of exertion in hot climates (p. B426).

Duration: Permanent until used; if it is used to put out a fire, for instance, the steam created is ordinary water. 
Cost: 3 per gallon created. 
Prerequisite: At least 6 other Water spells.

Item 
Staff, wand, or jewelry. Usable only by a mage.  
Energy cost to create: 800.

Creates pure water out of nothing. This water may appear in any of several forms. It may appear within a container, or as a globe in midair (it falls immediately). Or it may appear as a dense mist of droplets; in this form, one gallon of water will extinguish all fires in a one-yard radius. Water cannot be created inside a foe to drown him!

Duration: The created water is permanent. 
Cost: 2 per gallon created.
