The Complete Guide to T-Rex
This stand-alone, world-neutral d20 supplement explores tyrannosaurus rex as a powerful fantasy creature. It includes both historical interpretations of the species, from the sluggish tail-dragging form to the fleet-footed predator, along with expanded rules for intelligent T-rex that form alliances, remember treachery, and build dynasties. The supplement also presents alternate possibilities, including reptiles that grow throughout their lives and survive to extreme ages. It provides the background and game rules needed to use these creatures in a Broncosaurus Rex campaign or other d20 setting.
