Not exactly sure what you are looking for. If you want ways to incorporate manny DnD worlds I reccomend the following three products: Manual of the Planes, Player's Guide to the Planes and Portals & Planes (from Fantasy Flight Games).Kapture said:Anybody seen a project or hacked out a d20 based system for dealing with "dimensional rifts?" I'm wanting some rules for my rifts.
Okay, now I am strongly going to reccomend Portals & Planes for your D20 needs. It does have you covered in that department.Kapture said:What I'm looking for is the: Magic so strong/terribal/a scientific mistake it/that caused a rip/tear/hole in the time space continuum thing. Aweful things happening/spewing out as a result. Accidental/catastrophic rifts. I'm looking for a formulaized rule-set, to compare to what I've been thinking of doing.
