Building an oracle and looking through the Channel related feats I see stuff like Selective Alignment Channel (Channel can harm/heal Outsiders of a given alignment sub-type) and Elemental Channel (Channel can harm/heal Outsiders of a given elemental sub-type).
Does that imply that Outsiders[good] or Outsiders[air] usually wouldn't be affected by me channeling positive energy, that I'd need either of these feats to affect them?
Or does this just offer the flexibility to now target (Outsiders) by sub-type instead - bypassing my party in the process?
Channeling energy causes a burst that affects all creatures of one type (either undead or living) in a 30-foot radius centered on the cleric.
I assume Outsiders are 'living creatures'. Looking at the Outsider creature type the only "special" rules seem to be about resurrection - not healing effects or channeling. Neither do I see anything in the sub-type description (say - 'good' or 'air').
So for now I assume I will affect Outsiders when I channel positive energy for example - and the feats just offer me greater control to target (say, in a scenario where I wanna heal 3 Outsiders[good] and cannot exclude a bunch of Outsiders[evil] using Selective Channeling)? Is that the use case for these feats?
