• High tier Martials can have class design space to CHOOSE a magic item.
It is a bit iffy to explain HOW nonmagical characters can guarantee a magic item. Maybe call it "fate"? Maybe the magic item somehow finds them, for some guaranteed reason? The explanations needs work to sound plausible for a nonmagical character.
But in principle, it is ok for a Martial to do powerful magic, by means of a magic item.
I also think this is why, making "spells" and "rituals" two different design spaces, and allowing Martials to try perform rituals solves many qualitative differences between Martials and full casters.
That's what downtime activities are for.
