They are Arcane skills from Final Fantasy XII
Arcanist lore from http://na.finalfantasyxiv.com/pr/game/#!/magic/content
Arcanist Adepts of the art of arcanum derive their might from symbols of power born of geometric techniques hailing from across the southern seas. Held within occult grimoires, these symbols lend shape to the arcanist's aether, thereby allowing him to produce myriad powerful spells.
Using the selfsame symbols to unlock the latent power contained within gemstones, arcanists are also able to summon forth the familiar known as Carbuncle to carry out their bidding.
How does Bio, Miasma and Poison spells fit with occult power and Arcane Magic.
And you even tried using that argument as to why an arcanist can't be a tactician, when the class content includes dialogue and info about using your debuffs and DoTs to disable an enemy. The lore you quoted doesn't even support your argument...

Y'all be posting in a troll thread.
Because neither are relevant. You have categories; Black, White, Summon. Sort your spells and go to town that way.
