”Not really, but if you focus the spell on some sort of crystal, it can function as a reservoir that you can just add more magic to. There’s a reason so many magical artifacts have gemstones and such. For most artifacts, since they’re used as focii or catalysts, they recharge during normal use. For something like this it might be fairly large, though, and recasting the spell isn’t a big deal. I’m more concerned about your end.”
