Art from page 22 of the TME Expansion Rules We’ve included the same rank advancement matrix as shown on page 34 of the TME Hub Rules for ease of access, although the subsequent rank gain bonus matrix has been expanded to include all the new character types, as well. If you’re new to The Mutant Epoch and want an explanation of experience factors and rank advancement, we encourage you to read the brief write up on page TME-34, however a word on Experience factors is in order. Some say that it is too easy to go up in rank, or level up, in The Mutant Epoch and Outland System, especially compared to other popular role-playing games. Indeed, going from first rank to second rank can be rather swift. The reasoning behind this is that to gain the 60 experience factors needed do so means a newbie post-apocalyptic character must survive several brutal, potentially deadly fights. For example, imagine surviving a hand to hand battle with a black bear, EFs (Experience Factors) 50, or fending off several ferocious mutant dogs (EFs 18 each) or a whole 1st rank party enduring the onslaught of a mutant giant known as a garnock (pg TME-156 with 125 Efs). https://www.outlandarts.com/expansionrules.htm
