Lusus Naturae IV
A bestiary for the Throwigames Simple Roleplaying System, covering powerful monsters and beasts with PR43 and above. It completes the initial series of creature guides and focuses on the most difficult foes found in the game world. Each entry provides suggested rules, statistics, difficulties, numbers, and rewards for the game master to adjust as needed. Most creatures receive concise descriptions, while unique creatures are detailed more fully. The guide assumes a harsh setting where material rewards are scarce.
