I think it's ideal to hit overload saber, then 2 hits to apply the first two stacks, apply the third stack with cauterize and immediately pop Zen. That way all of the ticks for Zen crit on 4 stacks worth of burns (3 OS and 1 Cauterize). I haven't parsed the logs to see if this works the way it seems like it should.

Never tell me the odds....

It's a known bug that Scatterguns and Vibroknives don't RE properly.

I will roll a consular the moment it can be an Ithorian.
