A rules question for y'all regarding the interaction of these 2 feats:
The Orator feat clause, "You can use a Linguistics check in place of a Bluff check to tell a falsehood or conceal information" .... would this allow you to use a Linguistics check in place of a Bluff check for your Cunning Caster roll?
Since "concealing information" seems to be the intent of Cunning Caster's primary focus.
Not clear, as a GM I probably wouldn't do it. But I also don't like it to be easy to conceal spell casting either.
I would say they would not work together, because Cunning Caster seems more to me to fall under the "Perform Inconspicuous Action" subheading in the Bluff skill. Plus you aren't using your words to conceal your spellcasting (and utilizing your power of words is the whole intent behind Orator), but rather simply trying to hide somatic and verbal components of your spells.
