(Not updated for 1.3.0) Resolute Technique, Unwavering Stance.
This is a build which requires the Wings of Entropy and will try to get the right balance between offence and defence. Damage can be quite huge, but focus on defence as a priority and try to get high block chance. I have not fully tested it but even with a crappy skill tree it worked very well.
(Not updated for 1.3.0) Resolute Technique.
This build is built around max block and block effects combined with Cyclone. Aim for lots of attack speed and Armour/Evasion gear. Requires Bringer of Rain and The Anvil, and optionally Rainbow Stride for Spell Block.
(Not updated for 1.3.0) Iron Reflexes.
A Duelist with insane attack speed (original guide claims 24 hits per second). Uses Double Strike and Life Gain on Hit with Melee Splash, Multistrike, Faster Attacks, and Blood Magic to heal quickly in proportion with the amount of enemies. Able to run auras as well.
