Elixir Field misnamed.

snip.

You don't have to take the name literally.

Ah, I see. So let's call Fire I "Field of Death" because if you use it a lot on many enemies, you create a field of death with it.
Also, let's rename "Esuna" to "Aphrodisiac", because your group will love you if you use it properly.

Those sound so lame. Nice try though.

EDIT: Fire and Esuna have been recurring name spells in previous Final Fantasies while the abilities like Invincible, Defender and Destroyer I'll assume have been in XI only. Naturally, It would be awful to rename both Fire and Esuna.

Lame is subjective. I find german song lyrics lame, but my father loves them. I am just making fun of your attempt to make connections between the functionality and the name, because they're so counter-intuitive that they're proving my point of these names being misleading.
