Colossal
A bestiary of 13 mythic monsters presents massive challenges for fantasy roleplaying campaigns, ranging from oversized vermin and prehistoric beasts to planar predators, behemoths, the legendary tarrasque, and Jormungandr, the Midgard Serpent. The creatures span challenge ratings 10 to 30 and include threats that ravage the air, land, and sea. The supplement also provides alternate rules for creature size and shape, along with a combat climbing system that lets heroes clamber over and cling to colossal opponents.
