Fantastic tabletop roleplaying games, be it classic dungeon crawling systems like dungeons or spectacular superhero role-playing games like Mutants & Masterminds, often have rules and game mechanics to represent people with superhuman abilities such as magic or mutations. These “superpower rules” are generally the end product of countless hours of playtesting, carefully calibrated to be fun for players but not so overpowering as to invalidate other superhuman abilities in the RPG. However, it is possible for DMs and/or players to create their own homemade superpower rules for their own original RPG campaign; They just need to understand what makes certain superpowers interesting and how they fit into the core principles of the game system they are using.


Not long after release and resounding success from early on dungeonsTabletop game designers jumped on the bandwagon with their own RPG products – dungeon-crawling games with simpler or more complicated rules than D&D, along with RPGs built around genres alongside sword and sorcery. The first role-playing games in the superhero genre, Superhero: 2044 and villains & vigilantes, was released in the late 1970s and was packed with interesting, unique rules for creating superhero characters and simulating the crime-fighting stories so iconic of Western comics.

When designing superpower rules for tabletop roleplaying games—what these powers can do, what dice players should roll when using them, how often these powers can be used—GMs and players should always try to understand the basic design principles of the roleplaying system that they are use to ensure that the forces they design are balanced. In the rules of dungeons 5e for example there is an unspoken design concept called “Bounded Accuracy” where a player rolling a d20 on skill checks, attack rolls or saving throws should not get a higher result than 31, even with attribute bonuses, spell buffs, enchants items and so on.

Design tips for superhero tabletop role-playing games

Most tabletop RPGs are inherently about growth and ingenuity. As a classic RPG campaign continues, player characters “level up,” unlocking new abilities while improving the effectiveness of old abilities.
