You just have to find the right people to fight. Bridding as 1 defence isn't nearly as complex as main bridding, and it's pretty cool to down the other player with a common rambo spec. Just look for the people with god robes, and try to fight in the extra hard wilderness worlds. If you want to excell in ko power and options I would reccomend barrage, and get close. Pull out runes knives and get his hp low, quickly whip out dragon darts for a singly hit followed by a rapid crossbow. If the crossbow hits high enough go for the dds combo, it's rather fast but not instant. Bring a phoenix necklace to avoid getting speccd out, and always bring rocktails to fight, remember to eat one before you fight. Don't forget mystic might, eagle eye and ultimate strength, they help your hits plenty.
