Since the start of 3E, which (non-core) book have you used the most?

[Gnarlo]

FRCS and MoTW, my players run heavy in Druids and Rangers

/gnarlo

 

[bwgwl]

Defenders of the Faith and Sword & Fist, but i probably only used each of those no more than 2 or 3 times total. everything else even less.

my campaigns have been 99.9% core or homebrewed.

 

[AussieDM]

Forgotten Realms Silver Marches - considering I am running a campaign there...

All the other FR supplements do well and the splat books

 

[TroyXavier]

Psi HB, MOTP, and FRCS

 

[Cthulhu's Librarian]

For my characters, I've used:

Book of Eldritch Might 1 & 2
Kalamar Players Guide
Song & Silence

Our DM has used:

Tome of Horrors

 

[Seule]

Most games, the Splatbooks (S&F,T&B,DotF,S&S, and MotW). In the game I run, the Psionics Handbook by far, as I've replaced Arcane Magic with Psionics.
