"Oras: Select three feats that you do not have but whose prerequisites you meet. Once per day as a move action, you can gain the benefit of one of these feats for 1 minute. Each time you gain a level, you can replace one of these three selected feats with a different feat that you don’t have but whose prerequisites you meet."
Looking at RAW, it can be interpreted that each time a player chooses to activate a temporary feat that includes "Choose a/n X" as part of the benefit, that character may choose a different X.
For example, a player selects Skill Synergy as one of the feats granted by Ora's Blessing. The first time the player activates this feat, they choose Survival and Stealth as the additional class skills. Would they be able to choose different skills the next time this ability is activated?
Adaptive Fighting grants a similar ability for combat feats, but there are many more "Choose an X" options available to this version of Divine Blessing (including Adaptive Fighting, which compounds the issue).
Thoughts?
Edit: I see that there's a post from this past weekend that touches on this question, as well as a question about Adaptive Fighting, but there's nothing definitive as far as an answer goes. Should this post need to be merged with one of the others, that's fine.
