From publisher blurb:
In a world devastated by apocalypse, survival has a price. The landscape is twisted by toxic environments, radiation, and unknown forces, leaving creatures—and even adventurers—changed in disturbing ways. The characters who roam this hostile world do so at great risk, often bearing the marks of the wasteland itself: mutations. These mutations, a mixture of animalistic traits, degenerative conditions, and bizarre physical alterations, can shape characters in ways that are both advantageous and harmful. While some mutations grant new strengths or strange abilities, others come with debilitating consequences that challenge both mind and body.
This booklet introduces a random mutation system for your post-apocalyptic D&D 5e campaign, giving you a structured way to incorporate these physical changes into gameplay. By rolling a set of dice, players can discover what kinds of mutations their characters might develop as they navigate a world rife with exposure to mutagenic forces. Mutations are never entirely within a character’s control, and with each exposure, the body becomes more unpredictable. The result can range from enhanced senses, new limbs, or animal-like features to painful degeneration, loss of function, or deteriorating health. While mutations add depth and complexity to a campaign, the randomness ensures no two mutated characters will ever be alike. But beware—just as the wasteland takes, it can also give, and the nature of these gifts may be double-edged.
These rules are designed to enhance the role-playing experience and create unique challenges for both players and Dungeon Masters. Whether beneficial or detrimental, every mutation is a reflection of the environment’s impact, and how characters adapt—or fail to adapt—will shape their journey through the ruins of civilization. Use these rules to add tension, excitement, and a sense of unpredictability to your game, but always with the understanding that mutations are meant to complicate survival in this dangerous new world.
This is an guide for 5e for the Post Apocalyptic era handling radiatio, mutagens, mutations, with advantages, disadvantages, and random chances for each.
