How does the Skalds Inspired Rage interact with the rage power Auspicious Mark?
The wording on AM: The barbarian has been marked by the spirits, as indicated by an impressive tattoo, scar, or birthmark she possesses. Once per rage, as a swift action that costs 2 rounds of rage, the barbarian can call upon the spirits’ favor. Using auspicious mark grants her a +1d6 bonus on one d20 roll she has just made. She can call on the auspicious mark after seeing the result of the d20 roll.
Does that mean every time a party member uses AM it drains 2 rounds of rage from the Skald? or just when the Skald uses it on himself?
Is everyone in the party able to use it once per rage or just one use by one individual per rage?
