The Scythe Sin is not a new build, people have been running it for a very long time. It works well because it provides an enormous amount pressure to the opposing team, via direct damage and spreading conditions. You have a %80 critical strike rate with a weapon that does 41 damage on a critical hit. Factor in the other bonuses and your average damage per hit is between 90-110. Blind doesn't effect this build because of Assassin's Remedy, which removes a condition every time you use a skill. This build depends heavily on a monk or ritualist to keep you alive, as it has no defense or healing. If you find you are dying too quickly, you can swap in Critical Defenses for Critical Eye. Be sure to keep your enchantments up as Wounding Strike and Mystic Sweep are less effective without them.
I use a 20/20 Sundering +30 health scythe and radiant armour. You can also run a minor Critical Strikes rune in order to maximize your health.
