I think the description of "Greater Magic Seal" is wrong. What it says is actually the effect of "Triplet Maximize Boosted Magic: Magic Arrow".

During his buffing before attacking Shalltear he casted TMBM:MA right after GMS. But as we know Magic Arrow will fire immediatly after casting, which didn't happen here.

So I think the real effect of GMS is to seal the effect of the next casted spell until the caster release it. The advantage it provides may be that it's faster and easier to release the seal than to cast the intended spell directly, especially during a heated fight. Also you can spend your MP beforehand and give you extra time to regenerate those MP back, insted of having to spend it during the battle.
