Traits are fun things that give characters a bit more uniqueness and depth. They are COMPLETELY optional, and have positive and negative aspects.
Each character may choose up to two traits, not including backstory traits given to the character by the DM.
General Traits: May pick more than one. This includes Flaws, which allow an extra feat to be taken. Effects are primarily roleplay-related.
Genetic Traits: only one of these may be taken per character, and only for characters of the species listed. Includes Bloodline traits and Super-Mutations. Effects are split between gameplay and exposition
Regional: These are based on the region that the character is from. They will likely coordinate with backstory and roleplay, but do not necessarily have to.
