Energy Wave is listed as doing 13d6 damage on p. 104, but only 13d4 on the list of powers on p. 71.
The Soulknife is listed as having Listen as a class skill on p. 29, but as a cross-class skill on the chart on p. 36.
The example of a specific weapon choice that a Soulknife could apply to the mindblade on p. 27 is Weapon Specialization, yet this feat is only available to a fighter of at least 4th level, so only multiclassed fighter/soulblades could take it. This is not an error strictly speaking, but could be clarified, particularly as this clarification was made in the description of bonus feats available to the Psychic Warrior on p. 26.
Reality Revision is listed both as a 9th level Psion/Wilder power and as a 9th level Seer Power in the power lists on p. 72-3. I assume the latter listing is an error.
Second Chance is listed as having an XP cost on the powers list on p. 73, but not in the description of the power on p. 131. Also, the duration of the power says "1 round/lvl or until discharged" yet the description of the power states that the rerolls can be made once per round.
The character sheet for Shaper in the bonus expansion downloads lists Knowledge (Psionics) as a skill that is usable untrained (with no ranks in it).
Also, p. 185-6 says that astral construct menu choices do not stack unless the ability notes it stacks. None of the abilities on menus A, B or C note that they stack, as far as I can tell. This isn't an errata, but seems unnecessary unless there is a dragon article to come that will give new cool menu choices for astral constructs.
