So the skald has this bit at the end If their rage powers ability.
If the skald has the ability to rage from another source, he can use his skald rage powers during that rage as well.
Now a bloodrager's is a rage. So could you use your rage powers in a bloodrage?
bump
If you're asking if a bloodrager could rage during a Skald's Raging Song and benefit from the Skald's powers in addition to their own, yes except for a couple things that will only become available once the Skald reaches level 20.
Master Skald (Su)
At 20th level, a skald's inspired rage no longer gives allies a penalty to AC, nor limits what skills or abilities they can use. Allies with rage class abilities may use features dependent on those abilities without restriction, such as a barbarian's rage powers and a bloodrager's blood casting and bloodline abilities. Finally, when making a full attack, affected allies may make an additional attack each round (as if using a haste effect).
So the barbarian could rage under the influence of the Skald's Raging Song, but the Bloodrager couldn't cast spells in the same circumstance until the Skald reaches level 20 first.
I'm asking if I'm a skald 3, bloodrager 3, can I bloodrage and use my skald's rage powers?
I feel the answer is Yes as worded in the ability, but I just like to put things out there to see if other's agree with me or not.
I feel like the answer should be yes as well, given the way rage class feature is defined by the Skald:
..If an ally has her own rage class ability (such as barbarian's rage, bloodrager's bloodrage, or skald's inspired rage)..
If the skald has the ability to rage from another source, he can use his skald rage powers during that rage as well.
To be clear, only the Skald benefits from rage powers derived from his other class sources or feats. You only share rage powers from your Skald class progression
The bloodrager rounds of rage should benefit from all rage powers inherent to the character.
