Type of Feat: General
Prerequisite: None.
Specifics: +2 bonus to Spot and Listen checks due to finely tuned senses.
Use: Automatic.
Special: A Boar animal companion receives Alertness for free at 1st level. Also, wizards and sorcerers get this feat temporary, while their familiar is summoned.
Bug Notes
If having familiar, unsummoning it will make you lose Alertness feat permanently. This is especially annoying for characters that want to enter into Harper agent prestige class. Tested with 1.05 patch.
