Hit a Nerve

Feats

At 20th level, an inciter becomes capable of touching the nerves of even the calmest and most balanced creatures, thereby inspiring his allies. His inspired rage ability no longer gives allies a penalty to AC or limits what abilities they can use. In addition, even if enemies succeed at a Will saving throw against the inciter's abilities, they still suffer half the penalties.
