This statement demonstrates you have some underlying misconceptions about the rules in general. As billd91 already pointed out (thanks for that, gave you some XP), this is a single target power, not an area effect power. Aside from that, mind thrust is a useful power, but it is severely limited in numerous ways. First, and most importantly, it has no effect if the target saves, limiting its reliability to targets with weak Will saves, which isn't everything maybe half of your opponents if you're lucky, and generally isn't any powerful villain. Also as Dandu has pointed out (would have XP'd you if I could) it is mind-effecting, which automatically cancels out a lot of traditional D&D opponents like golems and zombies. But I digress. Let's not turn this thread into a "Psionics R brokin!" discussion.As has been pointed out, it has [D] in its duration, so yes, you can. Honestly, a lot of your questions could be answered by a simple reading of the rules. This isn't even gray area stuff here. I mean no offense, but perhaps you need to research your questions just a tiny bit before asking them. Maybe you are very new to D&D, which is fine, but it isn't like these are nebulous rules we are talking about. About 10 pages of rules regarding magic (much of which also applies to psionics) in Chapter 10 of the Player's Handbook will probably answer most of your questions. And unless you are an extremely terrible reader, this shouldn't take more than 30 minutes. If you have time to play D&D, surely you have time to read something like this, particularly if you are playing a spellcaster.
Edit: As an aside, I don't think anyone playing a spellcaster has an excuse for not reading the complete description of every spell one's character knows thoroughly from start to finish at least once. A single reading of the fireball spell would have pretty much nipped this entire thread in the bud.
