I'm thinking it takes a special level of consistency to use this combo with throwing knives (Pass) Backstab is already an emergency ability - I don't need 2 (Pass) But this DoT, blind and weap combo I could make work. On top of them slowed, blind and receiving damage over time (in an AoE!), Monte Carlo has High Caliber rounds, which make aiming impossible for its targets. Sounds like a niche combo to me!
