The Dragonslayers are currently wandering around the Greater Caverns of Iggwilv's lair (The Lost Caverns of Tsojcanth).
They have been sent to recover the rumored "Golden Treasure of Iggwilv" which of course is Drelzna. I am of course keeping all the treasure (Demonomicon, the 6 books, Prison and Lanthorn) but I am also throwing in a copy of the Book of Vile Drakness.
I have been using the 3.0 version to expand the monster choices in the dungeon, figuring Iggwilv would have bound some demonic creatures to her lair. Plus, the original S4 introduced a lot of new demons to the 1st Ed Game and the BoVD added more to the 3rd ed game.
So I picked up the 4th Ed Book of Vile Darkness over the weekend to help buff up what would be in the game world version.
I have to admit, the 4e one does not compare to either the 3.0 version OR the 4e Demonomicon.
The 4e version is fine, don't get me wrong, but it lacks the gravitas the 3.0 version had.
I'll use the props that came with the 4e version, and I'll expand the 3.0 version to include the 4e (And really converting between the two systems is not that hard). I'll use the monsters in the lower levels, espcially if I plan to add on the Thaizdun bits.
Plus the Dragonslayers need the book because it has a ritual to summon Tiamat. They are all god characters, and the ritual requires the sacrifice of a "Rainbow Dragon" which at the moment they think is a Chaotic good faerie dragon. Have not decided about that one yet. They are just kids afterall.
Did I get my money's worth for the 4e book? Yeah, I feel that I did. There are some very neat ideas and some cool things for a 4e game. Not as much as I would have hoped for though.
Of course if I use the book in 3e, should I turn around and have it reappear in 4e or 5e? No idea yet. Let me get done with 3e first.
Oh. And my oldest son wants to go back to Mentzer Basic. It figures really, I have tried to push Moldvay/Cook Basic D&D on him for so long that naturally he would only be interested in the one box I never really pull out.
