I know what bind is, perhaps I should define what an exception is...not that I'm saying they ARE an exception, just that if they ARE...that is irrelevant.
In any case I don't intend to kill them evenly anyway, I want to kill the dark one first remember? Even with enrage, white will only hit for 5800, and without dark, I CAN ecchi thru the bind.. That's not even counting that if I understand it correctly, white will be supplying heal orbs to me too. So healing thru that with double ecchi's will honestly be a total cakewalk. Plus just cuz I'm not LEADING with luci doesn't mean I can't have mine as a sub to burst straight past that 20%.
Floor 1 will require luck for sure, but...doesn't it always? Aside from that, I honestly can't see anything tricky other than getting the dark one from 20% to dead. I CAN survive its heaven and hell and white's attack, but only barely. I'll have to have some good orb management going from that (save up gravities too), to killing it, even with a luci nuke since it only does 8%.
I'm just saying it wont be easy for sure, but it's not the doomed to failure thing for the reason you think it is....I'm not sure about poison though. why didn't that luci guy ever have poison orbs?
