Components: v.s.m (d: v.s)	-	CT: 1 round (d: 1 turn)	-	Save: None

Effect.Cleric: When the cleric casts a create water spell,
four gallons of water are generated for every level of experience of the caster,
i.e. an Adept (C2) creates eight gallons of water,
a Priest (C3) twelve gallons,
a Curate (C4) sixteen gallons, etc.

The water is clean and drinkable (it is just like rain water).
Created water will last until normally used or evaporated, spilled, etc.
Water can be created or destroyed in an area as small as will actually contain the liquid or in an area as large as 27 cubic feet (one cubic yard).
Note that water cannot be created within a living thing.

Destroy Water: Reversing the spell, destroy water, obliterates
without trace (such as vapor, mist, fog or steam) a like quantity of water.

MC: The spell requires at least a drop of water to create, or a pinch of dust to destroy, water.

Effect.Druid: The druid can create pure, drinkable water by means of a create water spell.
He or she creates 1 cubic foot of water for each level of experience attained.
The water can be created to a maximum distance of 1” from the druid.

DMG.druid: It is not possible to create water within living material,
i.e. it is not possible to cast the spell upon a creature and create liquid in any part of its body.
 

Question: Can a cleric create water inside a non-living object?
If so, what would happen if water is created inside a vampire?

Answer: The question about creating water inside a vampire apparent-
ly comes from the mention in the MM that a vampire
can be killed by immersion in running water. Unfortunately, the
AD&D rules do not address the question of whether an undead
creature is considered “living” for the purpose of casting Create
Water. The intent of the rules, however, is made clear by the
description in the DMG (p. 43) of the druidic version of the spell:
“It is not possible to cast the spell upon a creature” (presumably
including an undead creature) “and create liquid in any part of
its body.” In any event, creating water inside a vampire would
not have the desired (harmful to the vampire) effect, since the
liquid is not running water, as it would be if it came from a stream
or a spigot.

WSG: Obviously, a life-saver when the party runs out of
water in the desert or any other waterless environment. But remember
two important points: You can’t take it with you unless
you have something to carry it in, and you can’t make water unless
you have at least a drop of water to begin with. (Whether saliva
or perspiration qualifies as a material component in this case
is a matter for the Dungeon Master to decide.)
