Book of Bones
This 69-page supplement presents new creatures and creature templates for True20 campaigns, drawn from the war-torn world of Simarra. It includes undead, tainted beasts, mutated experiments, and other horrors such as gretchlaw, Baasi-Gholú, mazruk, and waste scorpions. Although rooted in Simarra’s setting, the material can be adapted for other campaign worlds.
