Tiers

All abilities are tier 1 unless noted otherwise. You can increase an ability's tier by adding upgrades to it. Upgrades are listed below the ability itself. Each upgrade increases the ability's tier by 1. You cannot have an ability with a tier exceeding 2 or 1/2 your level, whichever is greater.

Some upgrades have the "superhuman" tag meaning they cannot be talent or luck but must result from biology, magic, or tech.
