You have glimpsed the madness at the edges of reality.
Benefit: You gain a +2 bonus on Knowledge (dungeoneering) checks to identify the vulnerabilities and powers of aberrations, Knowledge (planes) checks to identify the vulnerabilities and powers of evil outsiders, and Knowledge (religion) checks to identify the vulnerabilities and powers of undead, and you can make such checks untrained. If you have 10 or more ranks in any of these Knowledge skills, the bonus increases to + 4 for the appropriate skill. In addition, you gain a +2 bonus on saves against fear effects.
Completion Benefit: Any sane creature that attempts to read your thoughts takes 1d6 points of Wisdom damage (Will DC 10 + 1/2 your level + your Charisma modified negates). In addition, the effect of any ability damage, ability drain, or penalty to your Intelligence, Wisdom, or Charisma is halved (minimum 1). You take a -2 penalty on Will saving throws. Whenever you roll a save against a mind-affecting effect, roll twice and keep the better result.
