While working on a character that uses the Skald class I had a thought. The class is a combination of bard and barbarian, they use song to grant themselves and others rage. At 3rd level they gain the ability called song of marching.
Song of marching
At 3rd level, a skald can use raging song to inspire his allies to move faster without suffering from fatigue. By expending 1 round of raging song, the skald invigorates allies within 60 feet, who may hustle for the next hour; this movement counts as a walk (not a hustle) for the purpose of accruing nonlethal damage and fatigue. The skald must continue to perform the song for the remainder of the hour, otherwise its effects end, but only 1 round of raging song is expended for that hour.
Skald's rage states
When starting an inspired rage, the skald chooses which rage powers (if any) to add to the song, and all affected allies gain the benefit of these rage powers, using the skald’s level as their effective barbarian level. The skald uses his skald level as his barbarian level for the purpose of selecting rage powers that require a minimum barbarian level. If the rage power’s effects depend on the skald’s ability modifier (such as lesser spirit totem), affected allies use the skald’s ability modifier instead of their own for the purposes of this effect.
So am I correct in my thinking that any rage power choosen should affect song of marching during its entire duration?
