dont know if someone have experienced this but i was playing with my socerer and saw this 2 bugs on this spell, one i dont know how exactly happened, but i think it was like this, i casted the spell and i was equiped with a magical weapon just when the spell finished i pressed the quickslot to put weapon away then i received a penality in my attack that i had to load the game to fix, the other bug is one that helps the player in the game, and i discovered by consequence of the first bug, the save game i mentioned that i used to fix the first bug was saved while the char was under effect of the tenser spell, when i loaded i rested to finish all effects and the message appeared : You cannot use that item, then some quickslots got emptys and when i saw there was a tenser sword in my inventory, i tried again loading and resting and every time i do that with the spell on i created a tenser sword on my inventory, so you can create with this the many tenser sword as you want not only is a very good sword but you can sell each for 19k.
I posted this here because maybe someone will send to the bioware and they may fix the bug
