Chapter 1, Page 2: Under Attribute Strata of the Universe heading it states that "The character with such an attribute gains the below listed bonus per attribute die to all rolls dependent on that attribute" it should read "gains the below listed bonus to all rolls dependent on that attribute".
Chapter 3: Toughness and Empathic Insight, Enhanced Perception, Psionic Endurance and Telekinetic Enhancement feats. Toughness has been clarified to read "You gain a one-time +1 H.P. per character level bonus..".
The psionic feats have been clarified via an asterix (*) reference which reads "Applies to 1 specific skill when selected, to apply to another this feat must be selected again."
Update! Chapter 4, Page 52: The Psi-craft skill entry explaining how to charge crystals is a little garbled it reads:
Charge Crystals: Using Psi-craft you can also charge crystals with psionic energy (mana pts; see Chapter 7) as long as you possess psionics (rank 1+). This is done by making a Psi-craft check DC 12 + 2 per pt you want to store. This process deals 1 KO pt per 2 mana pts you attmept to store that is if you fail you still lose KO pts. All charged crystal can only hold 1 power or 6 mana pts for small sized or smaller (within reason) and +1 power/+2 pts for each size up. They are also all single use items though mana pts can be drawn out and used in smaller increments speading out their use over several uses reducing the available pts each time.
The Clairfied version reads thusly:
Charge Crystals: You can also charge crystals with psionic energy (mana pts; see Chapter 7) as long as you possess psionics (rank 1+). This is done by making a Psi-craft check DC 12 + 2 per pt you want to store. This process deals 1 KO pt per 2 mana pts you attempt to store, if you fail you still lose KO pts (KO damage lasts 24 hrs). Storing a power simply stores the charge check DC - 12 for the desired power. All charged crystals can only hold 1 power or 6 mana pts for small sized or smaller and +1 power/+2 pts for each size up. They are single use items though mana pts can be drawn out and used in smaller increments speading out their use over several uses reducing the pt total each time.
Chapter 13, Page 140: Under the Size Class heading the second paragraph states:
Note that Natural Armor bonus for size can be applied to not only natural armor but also any damage reductions or damage resistance but not H.R. When the creature possesses no actual hit die and just H.P. then the Hit Die bonus +1 becomes a multiplier. Racial HD and a creature's Class HD are affected by it's size.
It has been rewritten to read:
If the creature possesses no actual hit die and just H.P. then the Hit Die bonus +1 becomes a multiplier and size penalties. Racial HD and a creature's Class HD are affected by it's size. Note that size and weight classes cannot drop a creature's HD bonus/HP total below +1 thus in such cases adjust to 1 or +1.
Animal Intelligence: The entry on Page 142 Chapter 13 for Animal Intelligence under the Animal creature category should read: The Creature has an I.Q. score of -5 or -4.
It's an editing error, a left over from the previous edition.
Unicorn "Bane" Ability: Page 150 Chapter 13 entry says "..possesses the bane weapon ability.." under the Unicorn Creature Template, Magical Horn ability. This is another editing error, it should have been deleted altogether, so simply ignore it as it is no longer described in the CRB as it was in a preliminary draft. Only mentioned under the Dragon Bone entry in Chapter 11 as "Dragon Bane Weapon (x2 damage to dragons)"
Chapter 15, Page 168: Under the Spiritual Possession uncanny ability a reference in parenthesis reads "(see exorcism spell and psionic)" it should read thusly: " (see Exorcism, below) ".
