Skills & the Five Trees

Starfield has no fixed classes: your build is defined entirely by five skill trees — Physical, Social, Combat, Science and Tech — with each level-up granting one skill point to spend. Every skill has four ranks, and unlocking a higher rank requires both enough points already invested in that tree and completing a skill challenge (such as a kill or usage quota) for that specific skill. This gates power behind actually playing your intended style, so early investment shapes whether you become a gunslinger, ship engineer, outpost baron or stealth infiltrator.
