Normally a feat represents a talent or an area of expertise that gives a character special capabilities. It embodies training, experience, and abilities beyond what a class provides. Demigods like every other race can receive these as well, however, they can also receive gifts from their godly parent represented in the form of a racial feat. At certain levels, your class gives you the Ability Score Improvement feature. Using the optional feats rule, you can forgo taking that feature to take this racial feat instead. You can take this feat multiple times and if you ever lose this feat's prerequisite, unlike normal feats, you can still use it.

Prerequisite: Demigod of good or neutral standing with your godly parent
