Which single non-core 3e book do you use the most?

[Morpheus]

Since I am starting an IK campaign, I'll have to go with the Monsternomicon and the IK Character Primer. By golly, AEG's Magic is getting a lot of referencing too...

 

[Destil]

Psionics hand book, though that should really be considered 'core' if you're using psionics, being in the SRD and all...

 

[pogre]

Epic Level Handbook

 

[VorpalBunny]

The FRCS, with Magic of Faerûn and Faiths and Pantheons coming in a close second. I can also see Races of Faerûn getting a lot of use when I get it in my grubby mitts.

 

[Eternalknight]

I primarily use Oriental Adventures, mainly because I am playing a monk.

 

[megamania]

Psionics book

Magic of Faerun

If thoughts Could Kill

Also use a lot of the stuff from the CC books

 

[johnsemlak]

Well, I'm currently playing in the FR, so the FRCS is seeing a lot of use, along with Faiths and Pantheons. The DM uses Silver Marches a lot too.

In my PBP campaign, I just downloaded From the Ashes (World of Greyhawk), because the DM is using that as a setting. I'll probably use that primarily.

 

[Ruavel]

I'd have to say Path of the Sword (FFG)... although having recently acquired Path of Magic, I can see that rapidly taking over given my tendancy to play arcane spell casters and use the same as BBEG when I DM...

 

[Nightfall]

Considering I play in a non-core world, obviously I use a lot of Scarred Lands stuff. But there are others I use, such as BoEMs, and recently BoHM. Plus Tome of Horrors.

 

[Zarrock God of Evil]

I use the FRCS extensively. As I'm currently running a RttToEE campaign I use that adventure book all the time now as well...

Dragon Magazine sees a lot of use as well ...
