Yeah the telekinesis spell works great bypassing whatever puzzle is on the floor. I've done this trick at least four or five times, I still can't figure out the damn puzzle. As for the ring itself, the enchantments it has are crap.
Lol... Ignite is crap... ok.
It's the only ring I'll wear on legendary difficulty. Right now my current build has Augmented Flames 2/2 and Intense Flames along with Aspect of Terror in the Illusion tree, which pushes the damage of Ignite to 21 per second for 15 seconds. With only Apprentice perked in Destruction, that's 315 damage total for 15 Magicka. That's significant. Far from crap. Plus it stacks and none of my math took into account Dual Casting.
