Prompted Backstabbing

Feats

At 8th level, an inciter guides his allies by calling their attention to his enemies' weak points. All creatures under the effect of the inciter's inspired rage ability can now make sneak attacks, as the rogue ability of the same name, dealing an additional 1d6 points of damage. This additional damage stacks with other sources of precision damage, but the total number of sneak attack dice cannot exceed half their character level (rounded up). The damage increases by 1d6 every 5 levels thereafter up to a maximum of 3d6 at 18th level.
