[Snake]

Yeah, but, that's with Derg's tune-down on Cobra in mind. (2 dances if main class, 1 dance if off-class.) And besides, if the enemy's a Monk in this case, they can Sun Flare to blind.
Ruby Beam, just run behind them and use it while hoping they don't have Watchful Eye.

What I mean is, if Snake Dancer triggers, they dodge damage + effects. Or just make them unable to avoid the infliction of KD, Immobilize and Blind, specifically.
