Link nods. "Two runes make bombs. The other four do different things. Like magnesis."

He taps on the rune to demonstrate. It summons forth what looks like a giant, flowing blue magnet, which he uses to pick up something nearby made of metal.

Which, as it turns out, is a a door off of one of the truck's they just attacked. The magnet seems to attach to it like a tether, and the door floats up into the air like it weighs nothing at all.
