This just baffles me. I have fire and frost equipped but I don't know if i'm supposed to aim at the crystal, that didn't work, aim at the circles on the ceiling, that didn't work. There is no light. These puzzles usually don't baffle me but this one is ridiculous. I prefer to fight, lol. The guide is of no use because it doesn't explain, shoot fire/frost at what, for how long, etc. Where is the light, really, where is the light. Help, please.

i've done it twice and its tricky, but this is how i do it, don't try to line up all 3 beams at the same time, first line up one beam to a spot on the celing, then use the button to rotate the part of the roof until it lines up with the beam, them use the spells to angle the next beam to a spot on the ceiling, then rotate the cylinder to it, then do the same for the last one...don't try to line up all 3 beams at the same time.
