"Bracers of Extra Combat Maneuvers" cost 11,500-
You can can make one additional combat maneuver, regardless of whether the maneuver normally replaces a melee attack or requires a standard action. You use your full level in place of your base attack bonus to determine your CMB for the bonus maneuvers, though all combat maneuver checks suffer a –2 penalty when making one extra Combat maneuver. You may attempt a second additional combat maneuver, with an additional –3 penalty on combat maneuver checks. Finally you may attempt a third additional combat maneuver, with an additional –7 penalty on combat maneuver checks.
Ability comes form the Maneuver Master Monk Arch-Type price comes from the item "BRACERS OF THE AVENGING KNIGHT" in the UE. Critiques?
Holy smokes those are the cheapest, easiest, extra attacks ever.
It grants Flurry of Maneuvers with no prerequisites...
I'd stop at allowing the one extra at -2.
Yeah, maybe follow a +3 gives a 2nd extra maneuver, a +5 gives the 3rd extra, else drop those and only the 1 extra for that price.
