Questions in title. I'm not sure how much Ignore Defense is enough for any character, or like Boss Damage it's almost never enough?
For the 2nd question: My Zero just got 30% Ignore Defense, 7% stats, and 7% STR for his weapon (so total of 60% Ignore Defense, 14% stats, and 14% STR). I plan to cube it some more tomorrow, but for now I'm wondering if this will suffice until I can get Legendary. Obviously using Black Cubes, because RNG INT%/LUK% on a STR based weapon can go suck it.
My previous option included 20% Boss Damage (so 40% Boss damage from the weapon). I'm not sure if I made a mistake or not in not keeping this option.
