Hello!
I was experimenting with telekinesis today and I found out some pretty cool thing you can do with it!
Did you know you can grab salmon out of the water using telekinesis?
Did you know you can set off traps by throwing objects onto pressure plates with telekinesis?
Did you know you can grab objects behind a barred gate if you can't pick the lock on the door?
Did you know you can throw things at people and damage them (very little damage though more like a last second diversion)?
Did you know that you can pick up an item of value and throw it towards someplace and make guards or bandits check out the item while you sneak past unnoticed?

Does anyone else know any uses?

Have not tried any of those...But great ideas...

i might craft me some alteration cost reducing gear and do the thieves guild as a mage using this skill often... atm it s just to expensive to cast for me

Yea it's fairly expensive at lower levels but becomes much easier to cast later on. But it's very useful for thieves especially, perfect for causing diversions!
