4. The Complete Book of Necromancers
2nd Edition
1995
This book was jam packed with stuff, and looked at a great way to make NPC and enemy necromancers something truly villainous. The new kits were great, the new items interesting, the new non-weapon proficiencies essential (like venom handling), and everything from dark gifts, weaknesses, salient powers, to a map and dungeon at the end was great. It took a corner of the universe and fleshed the crap out of it in a beautiful way.
