I don't know why you'd consider not using a girl if trying to point out bests for a character/class build since imo the best accessory in the game in almost all cases is the incredible chantage perfume. For an archer I would use ignore height to keep distance (since here teleport is restricted). With the chantage and hp restore the archer would rarely ever have problems staying alive. She could also use the knight abilities to destroy all of the opponent's gear and stats, giving her the battle even w/o the need of many of her other abilities.
