Devotion feats:

[Thespianus]

No. As far as I have understood it, it's either or:

Either:

You have access to a Domain (for example, as a Cleric) you can sacrifice the domain granted power and the spells you get from that domain and instead pick the corresponding Devotion Feat.

Or:

You can spend one of your normal feats to pick a Devotion Feat.


Ninjas? EDIT: Yes, Ninjas.
