Arcanist, The Clever Strategist Class

Sometimes a big axe or a fast fist just isn't enough to overcome certain obstacles. Sometimes you need a calculating mind, a focused mentality... This is where the Arcanist shines. This class combines the efforts of a spellcaster and their Carbuncle ally to bring the pain or provide the relief to the battlefield as needed to ensure victory.
