i have tryed every thing.i have cooled the crystal 3 times

Need to cool or heat to move the rays. Once you lock one in place it won't move if you cool/heat it again. It's trial and error.

Ahahaaaaaah! Is that the one in Mzulft? *very angry memories*

Simple. Fireball spells and Ice Spike spells have 0% effect! ZERO! NADA! *rage*

If it is Mzulft, I got stuck there too. You have to use the Flame/Icethrower spells. (The ones that do damage PER SECOND, rather than 1 single blow.)

Perhaps I'm the only one dumb enough to make this mistake, but there you go.
