CRB FAQ：
Alternate Ability Score-Based Checks: If I change the key ability score of a skill (or other check), for example, if I change Knowledge from Intelligence to Charisma, is it no-longer an Intelligence-based check? Is it now a Charisma-based check? Generally yes—at the time of rolling a check, if you substitute the ability score, the check is now based on the new ability score. In the example, at the time of rolling, Knowledge would now be a Charisma-based skill and not an Intelligence-based skill for you, which would affect things like feats, spells, or items that grant bonuses on checks based on their key ability score (like circlet of persuasion). However, if you are adding a second ability modifier to a check, this is not the case. For instance, when adding both Wisdom and Dexterity on initiative checks, initiative is still a Dexterity check, not a Wisdom check. Also, this changes the check only at the time of rolling, so this does not change static class features or options made during character building such as your class’s class skills. Classes that receive “all Intelligence-based skills” as class skills, for instance, are the victim of sloppy writing, and furthermore sometimes effects might muddy the water by only changing the ability dependency sometimes and not others, which is why you check the new dependency only for a specific given roll.
