Are there options to give inspire courage to a bloodrager?
Of there's dipping bard or evangelist cleric, ..
And there's variant multi class bard.
Both options wouldn't really be preferable.
Would there be anything that's more organic to a bloodrager? Or any other way to get a similar level of buffing for the party?
3PP might be an option.
The skald won't help, our other melees will like to keep their senses (magus,...)
If you're just looking for something that grants the same sort of benefits as inspire courage. There's the feat Battle Cry which is pretty straightforward since it doesn't require any sort of multi-classing and the pre-reqs aren't awful. Alternatively, there's the feat Berserker's Cry. But it's a 3.5 feat and one of the pre-reqs would likely require DM approval.
If you're looking at having it to meet a prerequisite, there's a bunch of prestige classes that grant bardic performance but I don't think any of them would advance your bloodrager abilities so it'd amount to the same as dipping into another class.
Something similar ... Sure.
Bloodrager (Id Rager)
Emotional Focus (Anger): 7th level, Aura of Fury: +2 attack, -2 to AC within 30ft
Emotional Focus (Zeal): 7th level, Determination Aura: +2 to attack
Zeal has the best ability of the two but Anger might be more useful all around.
Thanks for the ideas.
Unfortunately it's not yet totally what I'm looking for.
The id rager takes away too much from the original bloodrager.
I like the cries but they don't seem to scale for higher levels.
3rd party? In Spheres of Might there's the warleader sphere, which you can gain via trading in a bunch of general feats rather like PF Unchained variant multiclassing or by archetypes like the stormlord.
Edit: alternately there's Dreamscarred Presses Path of War, see the martial training line of feats here and the golden lion discipline.
