Watery Double (Arcana) [Water]
Level: Mage 5, Water 5
Mana: 22. Base Success: 60%.
  To cast this spell, a wizard must target an opponent standing in a water square, whose Challenge Rating is less than or equal to her caster level. A watery duplicate of the target rises up -- a creature identical to the target with the aqueous template applied. This creature is not considered summoned, but can be dispelled. It cannot be ordered, and fights relentlessly with only one goal in mind: to slay utterly the creature the spell targeted.
   The watery double is immune to fear, mind-affecting spells and death magic. A given caster can sustain only one watery double at once, and the spell can be cancelled at any time.
