Elements, I wonder why they didn't do this.

[seiferalmasy2]

Chocobo/Moogle is a wind elemental (and you can place this on weapon and armour using elemental materia).

Holy is actually alexander (and not curative magic). Holy affects dark creatures. It can again be placed on weapon or armour.

You also have to understand that "element" is what the english translation team called it. It is NOT what it is in the japanese game.

Elemental > ぞくせい　> [in discussion]
[lit. Attributes. The unique characteristics inherent in the nature of the object in question.]

ぞくせい attribute, context, earthly life, growing gregariously, growing in clusters, secular surname, this world.

The original elements are: Fire, Air, Water, Earth.

But in FF games, the english localisations ahve made all the attributes an "element". IN other words, the confusion and problem lies in translation.
