I don't see how these are more than batteries...

From what I see, Laxus' Lacrima is just another store for Magic power. I see it more like a second origin type thing, another container that Laxus can tap into to access more Magic power that heightens his overall Magic power and allows him to use more advanced Magic... in this case, DS Magic. The Lacrima itself isn't doing the Magic, just holding the power.

The others are the same. The Lacrima in Nirvana sucked Magic power from the ground for the cannon and Jupiter sucked it from the Mages offering to supply power to the cannon... and Etherion I have no idea (we haven't been told how that works). As I see it, they are just like batteries, only their source is slightly different. Like if I charge my batteries from a wall plug or solar power... still a battery being charged, just a different source for said charge. They also weren't the ones doing the shooting... weren't they just the power source that supplied to Magic for the devices to shoot, which is why if they were taken out the cannons wouldn't work...??
