Not relevant in Early Access with the level 4 cap, but at levels 5 and 9 your Proficiency Bonus will go up by 1, which will increase all the relevant skills & saving throws you're proficient in (and your attacks/spell save DCs). This ~replaces the allocation of skill points present in previous editions. The only way to become proficient in skills you don't start out with are through a few select class features and feats.
