The Cagey Fighter
At Ten Ton Hammer, we love Custom Builds. They add flavor and resist the tendency to say there is only way to build a given class in Dungeons & Dragons Online: Stormreach (DDO). For The Swashbuckler, Darkgolem mixes the combat mastery of the fighter with the subtlety of a rogue. The result is what he calls a "cagey fighter" who picks on the most susceptible foes in the chaos of battle:
Combat Expertise can be applied to raise armor class even more. Improved Trip is a bit questionable, since trip is strength based, but it fits the concept of the build (a cagey fighter) so is added anyways. If not preferred, take Resilience instead. Evasion works very well with Dexterity. Good tactics would be to attack one foe then switch targets, attacking a second target and making best use of Sneak Attack.
