Besides the 3 core books, which sourcebooks/rules are you using in your campaign?

[Thorin Stoutfoot]

Core rules +

1. Psionics Handbook (only the monsters so far...)
2. Manual of the Planes (only the monstesrs...)
3. Forgotten Realms Campaign Setting (only the xp variant rules)

I don't own splatbooks, so I individually approve feats, etc from the players who've bought them. So far, the players who haven't bought splatbooks haven't been at a disadvantage.

 

[Trevalon Moonleirion]

The stack of crap I carry to every game I run:
*FRCS
*Lords of Darkness
*Magic of Faerun
*Enemies & Allies
*a 3rd party book a lot like E&A
*Monsters of Faerun

the rest of the WotC splatbooks that i own (Sword & Fist, Defenders of the Faith, and Tome & Blood methinks...not sure cuz a friend has them all borrowed) are availiable to be used, but aren't being used.

As for what rules I use...wow, this'll be interesting
I use just about everything from the FRCS, since I'm running the Realms. ditto for Lords of Darkness, MoF and Monsters of Faerun. E&A is all for those moment's where i go "oh crap! i need stats!"

edit--i forgot monsters of faerun!

 

[Nightfall]

Well I'd list my d20 stuff...but it take about a page. I will say I have REALLY enjoyed the Fiend books from GR, even if Legions is a little higher on my listing than Armies. Both though ROCK!

That's the thing... seems like 2E all over again. A bunch of rulebooks that just sit there gathering dust most of the time, to be used once in a blue moon. Cross-referencing is hard too, as you think you've seen a feat or skill before but not sure WHERE the heck it is in that 4' high stack of books.

 

[Flexor the Mighty!]

Armies of the Abyss & Legions of Hell
Manual of the Planes
Living Greyhawk Gazeteer(with the 1983 boxed set as well)
Creature Catalog
Book of Eldrich Might
We have all the splat books but they haven't even been touched at all, a waste of cash.

 

[The Sigil]

Me too...

IMC, stuff tends to fall into one of two categories... "extra goodies for the players" and "extra goodies for the DM".

Players first, broken out by class:

Barbarian - None yet
Bard - Enchiridion of Mystic Music (<shameless plug>helps that I wrote it, but gives the bard SOOOOO many more options</plug>)
Cleric - WotC Splatbook (hoping to replace soon)
Druid - None yet
Fighter - The Quintessential Fighter (fighting styles)
Monk - None yet
Paladin - WotC splatbook (hoping to replace soon)
Ranger - None yet
Rogue - None yet
Sorcerer - Book of Eldritch Might II (Sorcerer Variant), Spells & Spellcraft (Familiars)
Wizard - Spells & Spellcraft (Familiars)

Other books that occasional use for multiple classes:
Relics & Rituals (for some of the spells)
Librum Equitis I and II (for PrClasses)
Spells & Magic (Bastion Press)
Arms & Armor (Bastion Press)

Stuff that I use as a DM:

Creature Catalog (Scott Greene)
Alchemy & Herbalists (Bastion)
Traps & Treachery
T&T II (for the poisons)
Magic of Faerun (magic items)
Arms & Armor (magic items)
Monsters of Faerun
Mythic Races
Races of Evernor, vol. I
various bits and pieces of Dragon articles

And pretty much any adventure published for the old Boxed Set D&D system (converted by myself) to run my PCs through when I'm in a pinch. ;-)

This is everything that comes to mind off the top of my head.

I'm a little suprised you haven't used the Incarnate Sig, or perhaps a Penumbral Lord. I do think paladin wise, your players would enjoy the Coreanic orders, since they fit well with chivalic ideas. Course you might want to see Warren of the Ratmen, since I think you'll find it interesting. I definately think the Black Pelts would get a lot of play in many campaigns, ESPECIALLY as new underdark race.

 

[Davelozzi]

Core books, Psionics Handbook, If Thoughts Could Kill have all been used in play. I've allowed some spells from the WotC splatbooks and Relics & Rituals, but no one has bothered to prepare them yet. I am willing to allow several feats and a number of prestige classes from the WotC splatbooks and FRCS and although a couple of characters are aiming for prestige classes, no one has actually used anything from these books in play yet. I also use some home rules, and the Wheel of Time woodsman class.

 

[Davelozzi]

Oh yeah, I was just talking about rules above. I've also used two adventures so far - Sunless Citadel and Of Sound Mind.

 

[DM_Matt]

Everything WoTC is fair game IMC, unless specifically banned (of speed, mercurial, vorpal, coming back form the dead, etc...and as long as the PCs do not use instadeath, I don't either, except in cases of MAJOR Big Bads...its kind of a mutually assured destruction-type deterrent).

I also use select d20 publications, including prett ymuch anytihng by Malhavoc, esp Monte Cook and Bruce Cordell, and sometimes Rokugun.
