Hundreds of razor-sharp spikes eject from the tower, with incredible force, slamming against his forcewall, with almost enough power to damage it; they hang against the wall, for a moment, before losing their power, and sliding away. At touching the second rune, however, waves of all the elements explode from the tower, and several others, nearby, bathing them in alternating waves of fire, ice, lightning, sonic, and acid. Thankfully, Ama handles the protection for those... but, when the waves dissipate, there is now a small hole, about three feet on each side, in the wall, where the runes were. "Some door."
