Huh. His character doesn't seem overpowered to me at all. Just someone the guards would need plenty of ranged weapons against and the element of surprise. Could easily be solved by his character being blindfolded and cuffed (even tagged with some shocking device, but that might be overkill). Even with the strength of four of five men, he's hardly going to break through metal cuffs.

Makes me think if he was against my character in close range who has invisible razor sharp tentacles, it makes my character seem a bit overpowered... (Also, I added in another weakness for my character to try and balance it. If he's in unbearable pain he can't use his tentacles. Like if he's been stunned or badly hit. Just because telekinesis is more of a mental ability it seemed to make sense)
