The game is very good and gives me some new ideas for adventures, but this is not relevant in the following description. In this game, contact does not exist.
All powers affect immediately and depend only on attacker power score and victim saving throw.
Everything works OK and the psionicists are not more powerful than other classes. In one hand, is not obvious the way the game uses to decide when some power works since all calculations are automatic. I see that they do not always work, so, the defense modes are used in this case. I guess that a successful contest against the victim defense mode is required by these powers. Some of the powers are simplified too and the game has helps for each one, so, I list some of them.
