Final fight too hard?

My issue is destroying the meteors. You can't cast or do anything to them until they're about to hit due to the restriction on targeting enemies "too far" above or below you.

Run up the stairs?

If you're trying to blow them up from ground level, you're gonna die.

Counter argument:
"BUT YOU SHOULD BE ABLE TO CAST ON ANYTHING FROM ANY ANGLE WITHOUT RESTRICTIONS!!!!"

Anyway, that's pretty much what ya gotta do. There's no real "restriction" as people clearly are clearing this after they get a strategy down.
