Birthrights and Attunements are an expanded Feats list that may be made available by your DM. Birthrights are powerful boons your character has had since birth, whereas attunements are earned at set level thresholds just like Feats.

Birthrights are game-changingly powerful, so balance your encounters accordingly.

Attunements are similar in power to Feats, but are more geared towards unlocking specific niche playstyles, and are less game-breaking for a vanilla setting.

Gain one Birthright from Character Creation, and an Attunement at levels 5, 10, 15, and 20.
