Economizer relic in Final Fantasy 6. Equip this accessory and watch as even the most powerful spell in the game now only costs 1 MP. Combine that with the relic that lets you cast two spells in one turn and....yeah.
Blood swords in Final Fantasy 2 are pretty ridiculous too, carving off a set percentage of an enemy's max health (not current health) with every swing...and you can dual-wield em.
