The metamorphose liquids spell transmutes one type of liquid into an equal amount of a different, nonmagical fluid (water, wine, blood, oil, apple cider, etc.). The caster must touch the fluid itself (not simply its container) for the spell to take effect. Magical liquids are not always affected. Fluids can be transmuted only into nonmagical liquids; it is not possible to change a magical liquid into another type of magical liquid. Poisons may be rendered harmless through use of this spell, but the spell has no effect on poisons already consumed. Living creatures are unaffected by the spell, excluding those from the Elemental Plane of Water, which can be damaged under certain circumstances.
Note: This spell originally appeared in this form in the Tome of Magic for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
