What kind of range do you need to solo bosses?

i actually don't think i can solo him again, that was done with extra crit rate that raised my damage pretty big ._.

but yea, nothing stops you from trying, i found it fun to waste a marble and see how many statues i could down before the time was over.

Yeah that's what i did when i started PBing. Just seeing if i could finish ariel, and then seeing how far i could get the bean down, and then finally he dies.

Can't get an idea for improvement if you don't know the level of improvement you need for your goals.
