A skald is trained to use music, oration, and similar performances to inspire his allies to feats of strength and ferocity. At 1st level, a skald can use this ability for a number of rounds per day equal to 3 + his Charisma modifier. For each level beyond 1st, he can use raging song for 2 additional rounds per day.
Starting a raging song is a standard action, but it can be maintained each round as a free action. A raging song cannot be disrupted, but it ends immediately if the skald is killed, paralyzed, stunned, knocked unconscious, or otherwise prevented from taking a free action each round to maintain it. A raging song counts as the bard's bardic performance special ability for any effect that affects bardic performances. A skald may learn bard masterpieces.
A raging song has audible components, but not visual components. Allies must be able to hear the skald for the song to have any effect on them. A deaf skald has a 20% chance to fail when attempting to use a raging song. If he fails this check, the attempt still counts against his daily limit.
When the skald begins a raging song and then on each ally's turn, if the ally can hear the raging song, that ally must decide whether to accept or refuse its effects. This is not an action. Unconscious allies automatically accept the song. If accepted, the raging song's effects on that ally last for that ally's turn or until the song ends, whichever comes first.
At 7th level, a skald can start a raging song as a move action instead of a standard action. At 13th level, a skald can start a raging song as a swift action instead.
At 1st level, affected allies gain a +2 morale bonus to Strength and Constitution and a +1 morale bonus on Will saving throws, but also take a –1 penalty to AC. While under the effects of inspired rage, allies other than the skald cannot use any Charisma-, Dexterity-, or Intelligence-based skills (except Acrobatics, Fly, Intimidate, and Ride) or any ability that requires patience or concentration. At 4th level and every 4 levels thereafter, the song's bonuses on Will saves increase by 1; the penalty to AC doesn't change. At 8th and 16th levels, the song's bonuses to Strength and Constitution increase by 2. (Unlike with the barbarian's rage ability, those affected are not fatigued after the song ends.)
If an ally has her own rage class ability (such as barbarian's rage, bloodrager's bloodrage, or skald's inspired rage), she may use the Strength, Constitution, and Will saving throw bonuses, as well as AC penalties, based on her own ability and level instead of those from the skald (still suffering no fatigue afterward). Inspired rage does not allow an ally to activate abilities dependent on other rage class abilities, such as rage powers, blood casting, or bloodrager bloodlines; the ally must activate her own rage class ability in order to use these features.
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.
Song of Strength
At 6th level, a skald can use raging song to inspire his allies to superhuman feats of strength. Once each round while the skald uses this performance, allies within 60 feet who can hear the skald may add 1/2 the skald's level to a Strength check or a Strength-based skill check.
At 10th level, a skald can create a sense of growing dread in his enemies, causing them to become shaken. This ability affects only enemies that are within 30 feet and able to hear the skald's performance. The effect persists for as long as the enemy is within 30 feet and the skald continues his performance. It cannot cause a creature to become frightened or panicked, even if the creature is already shaken from another effect. This is a sonic mind-affecting fear effect that relies on audible components.
Song of the Fallen
At 14th level, a skald can temporarily revive dead allies so they can continue fighting, with the same limitations as raise dead. The skald selects a dead ally within 60 feet and expends 1 round of raging song to bring that ally back to life. The revived ally is alive but staggered. Each round, the skald can expend another 1 round of raging song to keep that ally alive for another round. The ally automatically dies if the skald ends this performance or is interrupted. The skald can revive multiple allies with this ability (either at the same time or over successive rounds) but must expend 1 round of raging song per revived ally per round to maintain the effect.
