Sorry if I butchered the spelling

Now my question about this particular affinity are the limitations of this affinity because it seems extremely overpowered.

If I'm understanding this correctly I, and i doubt it, anethuma affinity basically augments affects. Cut a single piece of paper hundreds are cut simultaneously. Toss a pebble in the lake, it turns into a tsunami so to speak.

What would happen if this affinity was paired with another, like a basic fire affinity. If someone cast a fireball would the anethuma affinity augment until it turns into fireball the size of a Boulder. Could it augment the force of an attack, turn a regular punch and give it the force of a cannon ball.

Or could the inverse work as well, diminish the force of an attack until it becomes nullified.

Since Valia died there isn't another user of this specific affinity, at least on Ithos. So im curious about the limitations and true powers because ut seems like one of the most powerful affinities in series, and it sucks it was never fully explored.
