Wardancer

Wardancers are sublime warriors, made even more deadly through their war dances. For these, the favored rituals of the Trickster, no rhythm is called nor are orders issued. Instead, the dancers instinctively enact a pattern of lethal movements, complementing the dances performed by the rest of the troupe. Each Wardancer leaps and pirouettes through the enemy ranks to music only she hears, gracefully evading her opponent’s clumsy blows and ending his life with an impossibly swift to strike of their own. To a Wardancer, even other Elves appear to be moving painfully slowly, as they complete their war dances at great speeds.
