A psion who chooses to remain more general in his studies of psionics is known as a generalist. While he does not gain the unique abilities each discipline grants to the specialized psions, he is able to broaden his powers and blend them in unique ways.
As long as you maintain psionic focus, you may manifest either of your chosen powers without paying a power point cost, but the power may not be augmented or affected by metapsionic feats. The competence bonus from call to mind is reduced to +2, the effect of catfall only treats your fall as 20 ft. shorter than it is, the duration of create sound is one round per two psion levels (minimum 1 round), and the damage of hammer is reduced to 1d4.
At 2nd level and every five psion levels thereafter, you gain a bonus feat. You must choose a metapsionic feat, an item creation feat, or Expanded Knowledge. You must still meet all prerequisites for the bonus feat, including minimum manifester level requirements. These bonus feats are in addition to the feats that a character of any class gets from advancing levels. You are not limited to the categories of item creation feats, metapsionic feats, or Expanded Knowledge when choosing those feats.
At 8th level, anytime you manifest a power, you may expend your psionic focus to add your Intelligence modifier on any check to overcome power resistance. This bonus increases by 1 every two psion levels thereafter.
At 14th level, once per day, you may manifest two powers with a single action, but the combined power point cost cannot exceed your manifester level and the two powers must be of different disciplines. The two powers must have the same manifesting time and if they have a target, the targets for the powers may be different.
At 20th level, each day when you meditate to regain power points, you may choose any one power from any class power list and add it to your powers known for the day. This power does not count against your number of powers known.
