Traits in Necromunda Underhive Wars determine the body shape of a Fighter and their capability and specialization of their career and weapon mastery. Traits are divided into three categories, Physical Traits, Mental Traits, and Martial Traits. Each category consists of various personalities that also include various buffs. So for example, if you wish to be a "Heavy Fighter", you must either choose to be Resilient or Athletic under the Physical Trait category. Players can only choose one Trait per category.
