Complete Priests Handbook (PHBR3) by Aaron Allston 1990.

Review: The first part describes creating mythologies and priesthoods, very useful in a role-playing intensive setting, less useful if it is less important to the campaign.  The CPHB does a good job of providing templates and questions to answer that help shape the mythology of a campaign.  Then the book provides 60+ sample priesthoods that could easily be dropped into a campaign.  These priesthoods all have special benefits and special hindrances that set them apart from basic clerics.  There is room for improvement and adjustment with these sample priesthoods but they are definitely very easy to use “off-the-shelf” with no modifications.

Several kits are included such as Amazon, outlaw, and noble priest.  The focus of the kits is on the social background of the character and how others may react to him or her.  This type of kit might be very useful to a campaign and it might not.  Also included for novice players are role-playing personality suggestions.  This is probably helpful in terms of giving novice players some ideas how to role-play.  Experienced players are told to skip the section on personalities.

One major contribution of PHBR3 to second edition rules is a proper war hammer.  The maul which costs only 5 gp and does 2-8/1-10.  (This compares with the 2 gp war hammer which does 2-5/1-4).  A maul is a two-handed weapon and is considered a polearm. 

Conclusion: 4 out 5 stars.  Good but not great.  Highly recommended for players with 2^nd edition priests.
