Found Wrath of the Immortals boxed set at the used bookstore. (Yes, I broke my streak)
Bonus elements inside include:
1. Extra copy of Book 2
2. A very large, homemade dungeon laid out in pen on graph paper. I believe there are something like nine levels. As with many of the papers I find in used D&D products, they smell every so faintly of hash. Also, the last level of the dungeon is sadistic. Checkerboard floor consisting of alternating glyphs of warding and fire traps. Holler.
Oh, and the previous owner felt the need to make about one hundred copies of the Immortal Record Sheet, only one of which is filled in.
RIFTS Denver, Session 2 is tomorrow. So far, playing a Body Fixer has turned out all right for me, even when I had to tranquilize a fellow player character with extreme prejudice.
