The Complete Priest's Handbook, Second Edition (Advanced Dungeons & Dragons: Player's Handbook Rules Supplement/PHBR3) 
Reviews
It begins fine with relatively good ways to make up your own pantheons of gods. This is helpful to an inexperienced DM, but for a seasoned DM or any DM using campaign settings providing unique pantheons, this is very little help.
Things go downhill from there. The sample priesthoods are pretty weak. Not one of them comes close to having the spells of a cleric or granted powers of a druid. If you're using 2nd edition rules, you're better off creating priesthoods under the guidelines provided in the players handbook.
Almost everything else is kits and Role-playing personalities taken from other sources.
Uninspired and unimaginative are good words to use for this book.
Numerous superior 2nd edition products are out of print, yet this
one still exists. Go figure.
In short, ignore the sample priesthoods, or at least give them more spheres and/or abilities, if you want your players to still be your friends.
The rest of the book is good. It provides mythos creation guidelines, so if you don't wish to play in Forgotten Realms or Greyhawk, you can create your own pantheon and mythology using the guidelines in this book.
The kits are not all that great, one of them even relying on the heavily flawed Martial Arts system from the Player's Handbook. But with a little tinkering, you can use them. Just about everything in here needs a little work, but it's not unusable.
It's a good reference for DMs who are creating their game world. For players, they will probably get little use out of it.
