Over the years, 13th Age has accumulated variant rules that the designers have shared with us. This page attempts to collect the variant rules in one place, summarizing each rule and providing a reference to the original source.
- Alternative Ability Score Array—Use this ability score array, which is better than the point-buy would allow, but on the bottom end: 17, 15, 14, 13, 12, 10. Source: 13th Age Glorantha p. 24.
- Force Salvo—Replace the adventurer tier feat with one that requires the wizard target each enemy only once. There are some other options offered as well. Source: 13th Age FAQ.

- Icon advantages—When rolling icon relationships, treat both 5's and 6's as advantages. When a you use an icon advantage, roll a d20. On a 1–5, the advantage comes with a complication (the equivalent of a 5 in the core rulebook). Source: 13th Age Quick Start Rules p. 11.
