Psion question

So telekinesis is a very situational skill that psions can have, and I got it. I was thinking of ways I could put it to use and was wondering if you could use it to block. What I mean by that is if I have a buckler can I ask a Marshall to use it for me and try to stop incoming attacks?

No.

Aw thought that would be something cool. It mentions you can't attack but says nothing about defending.

The Rule Of Interpreting Rules
When interpreting the rules of the game, the base assumption is that you cannot use the rules to accomplish something In-Game, unless a rule specifically states you are able to do so. For example, the 1st Rank Fire spell "Fire Strike" does not state it can be used to ignite flammable materials – therefore, you cannot use it to do so. This may be overruled by an OOG marshal that is monitoring an encounter, but only on a case-by-case basis – precedent does not matter in this rule. That being said, these rules have been updated many times over the years; there are bound to be loopholes, or technicalities that are not in the spirit of the rules. If you feel you find something that isn’t in the spirit of the rules, do not take advantage of the flaw, post it on the forums to be clarified.

Thanks gunner For explaining that.
Would anyone know a practical use for telekenisis than?

Over the last 3 events, various Psions used it to extremely great effect during rituals and RP heavy scenes.
