Its a little more advanced yea. Probably around the level of what a Summon is in terms of where it stands (actually Revolver is around that level in reality, its pretty much Sasha's akin to having gained a summon, something thats a slight bit more powerful than beginner stuff)

The problem is firing alot of rifle bullets at one time, its not exactly easy to fire a rifle bullet through a revolver XD (it would take a good bit more Mana certainly). 

And you are right, you guys are sorta blind, and that's my fault. Things will get more clear after this dungeon though (and plus, I admit that the blindness was both intentional and unintentional XD)
