An arcane duelist of 18th level or higher can use his bladethirst performance to enhance the weapons of as many allies as desired within 30 feet. The bonus provided by this power is +4 if conferred on two allies, +3 for three allies, +2 for four allies, and +1 for five or more allies. The power granted to each weapon must be identical. This ability replaces mass suggestion.
