If I can move heavy objects with my mind then I should be able to open stone sarcophagi like ones just above Withermoores soul jar in act 1.
I mean how are full magic damage parties supposed to deal with strength checks to open "heavy" stuff eh? It's logical to assume that telekinesis should work according to its own tool tip. There's no small print to say "so long as you only expect to move chests, barrel and boxes.
Cheers
