I've just got the new Champions of Balance book and have a question about the Planar Companion feat (on page 13, see also http://www.d20pfsrd.com/feats/general-feats/planar-hunter ):
Benefit(s): When you are on one of the planes you've selected as a favored terrain, you gain a +2 bonus on weapon attack rolls against outsiders native to that plane. You also ignore up to 5 points of damage reduction when making weapon attacks against outsiders native to that plane, except for damage reduction without a type (such as DR 10/—). In addition, you gain this bonus against extraplanar creatures you encounter and identify as being from one of your planar favored terrains, such as with a successful Knowledge (planes) check, regardless of what plane you or they are on.
So if you're on a 'favoured terrain' plane, you get bonuses against outsiders native to that plane.
But (third sentence), you also get those bonuses against outsiders native to that plane regardless of what plane you or they are on.
So, why does the first part of the feat need that wording at all (about being on the plane) when the last sentence says you/they don't need to be on the plane? Is is that being on the plane means no Knowledge (planes) check is needed, but being off the plane means you do still need to make a Knowledge (planes) check? Am I missing something?
