SE Whm is suppose to have water spells.

[desufin]

Shroud and Cleric's are, but Divine Seal looks more like Holy's aura.

Actually maybe it is water...but the point I was making is that Cure and Cure 2 are most definitively not water spells.

It very clearly has the blue water aura effect right as you cast it before the big shiny Divine Seal animation itself takes over. The only spell that doesn't seem to have a direct element animation on the character is Regen.

Edit: While not CNJ/WHM spells, Eye for an Eye and Virus are also water based.
