Cyclone Strike is the key to grouping up monsters, which will also spawn the Decoys required to complete the objective. Kyoshiro's Soul belt and Vengeful Wind are core to completing this Set Dungeon efficiently, so it is highly recommended to farm these two items if you don't have them already. The way I've tackled it above is to gear up for as much Cooldown Reduction/Spirit Generation/Resource Cost Reduction as possible, with Cooldown Reduction being the highest priority so you can Dash/Epiphany as much as possible. The Sunwuko Set Dungeon was another fairly simple one to complete, and I think I overgeared too much for this.

I'm not really playing Monk this season so I can't really test this without finding the right gear, so I'd love to hear if this is easier/harder than my old build. Be sure to still gather up the trash monsters by walking around in cirlces then spamming Cyclone Strike and when you encounter Elites, use one or two Wave of Lights to kill it (make sure not to spam this skill so you don't risk losing all of your Sweeping Wind stacks!).

I've also added the supporting items in Kyoshiro's Blade weapon, Pinto's Pride bracers and CIndercoat Armour to help out with bursting the elites. In its place I've selected Wave of Light - Explosive Light (you can use any rune really, it's there just as burst damage and additional resource reduction from Cindercoat). ***UPDATE*** I've updated the build guide and dropped Mantra of Healing - Circular Breathing (7 Spirit per second lost - 3 Spirit from rune/4 Spirit from Chant of Resonance passive) or you could drop Mystic Ally - Air Ally (which is 8 Spirit per second + active ability for extra 100 spirit, if you drop this you should wear Illusory Boots instead). You can find general Set Dungeon information and Set Dungeon guides for the other classes at my Set Dungeon Thread. Reduces the number of items needed for set bonuses by 1 (to a minimum of 2). When the initial impact of your Wave of Light hits 3 or fewer enemies, the damage is increased by 200 - 250%. Increase the damage of Wave of Light by 150%.
