Which D&D supplement do you most enjoy using?

[Psion]

XPH and Planes and Portals see a lot of use from me these days.

If it counts, Dungeon Magazine. I'm getting a lot of mileage out of the Age of Worms. Besides that, Lords of Madness is the book I most enjoy using. My players cringe slightly whenever I pick it up.

Demiurge out.

 

[Shemeska]

3e: Lords of Madness, Draconomicon, Manual of the Planes

2e: Hellbound, Faces of Evil, Factols Manifesto, Guide to the Ethereal

Probably the Book of Vile Darkness. Archfiends are just too cool.

Although...

Races of Stone is pretty darn spiffy, I loves me some dwarves and goliaths.

Good question, Xath

Technically, even though it's a 2e AD&D supplement published by WotC, I really like The Apocalypse Stone - not so much for the actual adventure, though, as for the ideas on cosmology and terraforming settings that it provides.

As a DM I love the Book Of Vile Darkness. Doing really nasty things to PCs is cool.

 

[Varianor Abroad]

On a WotC-only basis? Manual of the Planes. Boo-yeah!

On an "all-of-d20" basis? Tossup between Requiem for a God, Tome of Horrors, and Arcana Evolved.

 

[Imret]

From only WotC stuff, Unearthed Arcana or the Monster Manuals as a group.

As far as from everything sitting on my shelf, it's an even chance of being Central Casting's Heroes of Legend, my assortment of monster books, or the Campaign Toolbox.

Out of my entire collection, it's the hot new copy of Elements of Magic: Revised.
/shameless plug.

That would either be Arcana Unearthed (as opposed to Unearthed Arcana) or The Book of the Righteous. Both give me scads of ideas.
