That's somewhat similar to 'metamagic feat' in D&D.

Maximize : Increases the damage (maybe) of the spell

Twin, Triplet : Cast the spells 2 / 3 times at once.

Boost : Increses the rank of the spell. So if the target owns magic immune to low-ranked spell, that adding this metamagic will enable to ignore the resistance.

Widen : Widen the effect area of the spell.

Also there's a metamagic that ignores some magic resist of the target.
