What specific stuff from d20 products are you using?

[Eternalknight]

I use the character concepts from Mongoose's Quintessential books, as well as feats and prestige classes (mainly for villains) from many other products.

 

[heimdall]

My campaign:

Mindscapes/ITCK - Replacement for Psionics
Call of Cthulhu D20 - Cthulhu mythos integrated into story lines
AEG Good - Avenger & Defender Core Classes
Ravenloft (all) - Campaign will eventually shift with the coming of the Mists
Path of the Sword - a few of the Core Classes

 

[Southern Oracle]

I'm using the greenbond class from Arcana Unearthed, a wide selection of spells from the Books of Eldritch Might, and a variety of spells, feats, and equipment from Dragon magazine.

 

[Gothmog]

Hoo boy, lots.

FFG- the whole Path of ... series, Traps & Treachery I and II, Monster's Handbook, Spells & Spellcraft, City Works, and the .... Lore series. FFG can do no wrong!

AEG- Evil, Good, Mercenaries, Feats, Undead, Magic, Toolbox, and Wilds

Mongoose- parts from all of the Quint series, ED- Shamans, Slayers Guide to Undead, Ult Feats, Ult Prestige Classes, Ult Equipment Guide, Ult Arcane Spellbook

Green Ronin- Shaman's Handbook, Witch's Handbook, Armies of the Abyss, Legions of Hell, Book of the Righteous, Hammer and Helm, Secret College of Necromancy, Unholy Warrior's Handbook

Mystic Eye- Tarot Magic, Foul Locales series, Artificer's Handbook

SSS- parts of R&R1, R&R2

Necromancer- Tome of Horrors

Atlas- Occult Lore, Penumbra Fantasy Bestiary

 

[Sanackranib]

my campaign is set in the Scarred Lands so I use all that stuff + the quintessential books, mostly for the extra feats, PrC's, fighting styles and character backgrounds.

Man, that's a lot of stuff. You've got one heck of a collection

 

[HellHound]

Obviously, just about everything I've written in my own books is in our games, in addition:

the Blight Magic system from Mystic Eye Games (also being used as blood magic and for insane psions - look for rules on insane psions based on the Blight Magic rules in one of my upcoming books)

Weapons and Armor from MonkeyGods "From Stone to Steel" (I tried to use Bastion's Arms & Armor, and while I love the cool new stuff, the mechanics are more sound in Stone to Steel).

Psionic powers from If Thoughts Could Kill

Spells from Relics & Rituals I & II (but not the ritual magic)

Legendary Classes from the Path of... series (although little else)

Guild Statblocks & Prestige classes from Traps & Treachery I

All the feats by two in FEATS from AEG. (Excellent work, even if they have no clue of how to cite the Section 15 and ended up mis-citing my own OGC in said book)

And a bunch more, but I'm late for class...

 

[Psion]

Well, I used quite a bit more in my high level game. I'll probably getting back to using some things in my current low-level Second World (D&D/d20 modern crossover) game, but the current "typical" sourcebooks include:

- the D&D core books
- Arms & Equipment Guide
- d20 modern
- Second World Sourcebook and Masters of Arms
- Blood & Fists
- Tome of Horrors, CC2, Liber Bestarius for additional monster selection. Haven't used Monster Handbook this game yet, but probably will soon.
- My "big book of psionics" - My binder full of psionics PDFs (ITCK, Mindscapes, Minds Eye enhacements)
- Relics & Rituals, BoEM, and Necromancer's Legacy for additional spell selection.
- Will probably be using Quickshots and Tomb of Abysthor for adventure material soon.

As I move into different regions of the world, I anticipate using Stone to Steel, OA, and Nyambe.

In the Greyhawk campaign in which I play, our DM the ALmight Scyldsceafing permits non-WOTC products on a case by case basis. HE has permitted the following with regard to my character:

Spells: Spells & Spellcraft, Arcane Strife, Books of Eldritch Might (too numerous to mention by particular spell)

Feats: NBOF (anything goes), Asgard mag (Stories and Sagas), Quoth the Raven netzine (Higher Education).

PrC: Asgard mag (adventuring scholar) and Complete Book fo Liches (lich)

Familar: we will use the familar path rules described in Mongoose Familars book, but rejected the familar enhancement rules in Spells & Spellscraft.

Slavery: rules as describe in Chains and Misery as under negotiation

 

[Clint]

3.5 ruleset with some house rules. As far as other sources:

- The setting and adventure from Malhavoc's Banewarrens.
- The pantheon, clerical orders and holy warriors from Green Ronin's Book of the Righteous.
- A PrC from FFG's Path of Magic.
- The counters from Fiery Dragon's Counter Collections.
- One feat from WotC Defenders of the Faith.
- A weapon from Green Ronin's Hammer and Helm.
- A couple of spells from WotC's FRCS and Magic of Faerun.
- A couple of spells from Malhavoc's Books of Eldritch Might, but only the ones required by the Banewarrens, since much of the balance in the BoEM spell series was lost in the 3.5 upgrade.

And I'm waiting to get the Artificer's Handbook in the mail to hopefully replace the magic item creation system wholesale.
