There is no temporary bonus available for Inspired Rage/Raging song class feature as there is for Barbarian Rage or Bloodrager Bloodrage. Would be awesome to be able to add it to the Skald (and maybe put a level select on it for other classes to select if they have a Skald in their group so they can see the bonuses).
My Skald can not
a) show his own rage bonuses
b) add rage bonuses to other party member
c) invoke rage powers (lesser beast totem - add claws). The lucky Barbarian can do this…
