На 1 уровне вы получаете некоторые умения благодаря вашей первичной подготовке и обучению: они указаны в начале описания класса.
All gunslingers have a particular way they follow, a combination of philosophy and combat style that defines both how they fight and the weapons they excel with. At 1st level, your way grants you an initial deed, a unique reload action called a slinger's reload, and proficiency with a particular skill. You also gain advanced and greater deeds at later levels, as well as access to way-specific feats.
Gunslinger ways can be found here.
