Someone wanted this from me, so I decided to post it up.
History: The Zombie House Planar Campaigns I & II had these rods of wonder that gained effects as time went by. It was further discovered that these rods were made by the party's nemesis Tash, and evil wizard bent on taking over the planes through use of the planar super keys called "mogrites." Tash's specialty was rod creation, and he made three of these rods of wonder. Each of the three rods got "experience" as they were used, gaining effects that were then shared between the rest of the rods. Planar Campaign I party found one rod (I can't remember where), then the second on Tash's dead body when we defeated him at the end of Champaign I. In Champaign II, the new party eventually found itself on Tash's demiplane, where they found a rod of their own in his wizard tower. With all three rods in hand, they eventually came in contact with Dorian McKraken, one of the characters from the first campaign. He had the Alchemist's Cube (aka the Horadric Cube from Diablo II) in which three similar items could be placed in the Cube; the button was pressed, and the three items would be combined. They proceeded to do this with the three (now epic) rods of wonder, which thus turned into the staff of wonder. This staff was identical to the previous rods, except you roll on the table three times, and each effect happens.
The rod(s) and staff got many interesting uses, and, at times, made the campaigns very interesting.
