Adastra and Indigo were the ones that put out the first valid strategies. One was with CA arrow, the other with potency focus to land blind more reliably.
I ended up doing a hybrid and ran a 15+ attempts test streak with no losses, then several guild mates ended up going 3/3 with it.
Stats to aim for in this modding:
CD/offense set with a potency set
CD triangle
CA arrow
Potency cross
~200-210 speed, close to 100% potency.
You open with JKL's Stalwart Advance, followed by basic, Heroes Arise then Stalwart advance again. With more potency you'll land blind more consistently, but with CA arrow you have a saving belt even if you get the worst possible Vader opening of MM, AoE, Culling Blade.
