QUOTE
Cast an area on the ground that will amplify all Water element attacks and increase the Max HP of Water element characters.
* Deluge also enables the use of the Water Ball and Aqua Benedicta skills.
* Deluge acts as shallow water for skills Aqua Benedicta and Water Ball. While Water Ball consumes Deluge rapidly, Aqua Benedicta can be used endlessly while the spell on the ground lasts.
* Deluge doubles the duration of Blinding Mist.
* Deluge cannot be cast on a cell currently affected by any floor skill or ground targeted skill.
* Initial cast consumes 1 Yellow Gemstone and grants the Elemental Floor buff for the duration. Casting Deluge, Whirlwind or Volcano while the buff is active will not incur a gemstone cost.
Deluge makes blinding mist stay forever. You cant get rid of it even by removing deluge, you need to throw a Magnetic Earth to remove it.
