Apparently, Magus is so powerful that its constantly forcing his gloves off. Thats about the only reason I can come up with as to why Magus was always adjusting his gloves every battle.
Or they're too small, but with all the evil stuff in his busy schedule, he just can't find the time to go get a new pair.
Dont ya mean too big?
Actually, it's the way he focuses himself when casting spells. He does a more pronounced glove adjustment whenever he does big spells like Darkmatter. Basically he's so powerful simple enchantations aren't enough to draw out his spells effectively, unlike Crono, Lucca, and Marle who while powerful can cast spells without much real effort. Magus is just on a whole other league from them.
I always thought that his gloves had magic symbols on them, ones too small to see on a sprite anyway, and the adjustments were just him shifting them around until the one for the particular spell he was casting was prominent. Or, maybe instead of symbols, just visual representations of his various spells.
I always thought he was flipping me the bird. Made it SO much easier to justify kicking his ass earlier in the game.
If they don't fit, or if his gloves get blown off slightly from the power... why continue to wear them. Or at least get some decent ones that cover a bit of the arms.
