>it makes people more likely to "PLAYER KNOWLEDGE" the RP. Things that players know, that characters shouldn't. 

If I might jump in here for a bit; The term you're looking for  here is "metagame" or in this case "metagaming", which is indeed a very serious issue for roleplays, especially on freeform sites, along with power gaming. I would encourage you to  pm either Draco or Wisp in regards to further figuring the limitations of your character's powers so as to avoid someone suddenly having their character "conveniently" find a way around you character's abilities. 

As for the mentokinesis bit, while it does fit well with your character concept it's a bit of an overkill to have it be effective outright even outside of the kingdom of Lucifer. One of the common beliefs of mind control and other telekinetic and telepathic abilities is that the powers themselves are completely dependent on the willpower and mental fortitude of the user and the object said powers are being used on. A telepath could easily sway some average schmuck on the street if said schmuck isn't prepared for a mental tug of war, but let's say that the telepath tried using their abilities on a hardened fighter: The fighter might not have quite the same level of mental fortitude as the telepath, but he's likely going to have good deal of willpower which can present a challenge, but isn't impossible. The fighter's lack of mental fortitude makes them a tad easier to wrest control of, but that high willpower means that they can still resist to some extent, and that even the slightest lapse in concentration might be all that they need to break free

 Now, let's say we have a telepath try their abilities on a telekinetic with high mental fortitude but low willpower, again it'd be a challenge, maybe even more so than the fighter because the telekinetic understands the mind a bit better, but this too can be overcome with enough effort. The telekinetic's mental fortitude makes them a much more complex target and definitely draws out the time needed to ensnare them, but the lack of willpower means that the telepath can rest a bit easier than they could with the fighter.

tl;dr

Willpower = Harder to control but easier to ensnare. 
Mental Fortitude = Harder to ensnare but easier to control.

Not to say that you character shouldn't be nigh impossible to resist in his own home, just that it should be a little bit harder for him to work his magic outside of Lucifer.
