System-neutral & 5e Stats
We developed a simple decimal system of statistics, which makes it easier to adapt monsters to all types of role-playing games. This system is based on the relativity between the different monsters present in a bestiary, which allows the Game Master to have a fairly precise idea of the strength and abilities of a creature. In addition, this system allows the monsters to be adapted to the player levels. That said, digital versions of all monster statistics are also freely available for 5th Edition and other popular TTRPGs.
