I see your Yiazmat and raise you a final vergil fight in devil may cry 3 on dante must die (highest) difficulty. A succesful attempt "only" takes around 1-3 hours, however I have it on reliable source that Yiazmat can be beaten by punching in the right gambits and going out for a few hours.JasonKaotic said:To be honest, I think the one, true, factual answer to this thread is Yiazmat from Final Fantasy XII.
The boss takes 4 hours to kill, and has instant death attacks.
I challenge you to name a more tedious boss. I dare you.
Vergil 3 on the other hand requires almost monk-like focus and olympic level reflexes from the very first second until the last, as he can take out all your health in literally a blink. Keeping this up was mentally so exhausting I simply couldn't try more than once a day.
And than there's the grinding. I have no idea how much preparation is necessary to even attempt Yiazmat but for vergil 3 you ideally need a full stack of health potions (20) and holy water (30). Health potions are 20000 each and holy water 30000. The fastest way to grind money I found was to do vergil 3 on easy perfectly, which took about 15 minutes and got you 10000. Applying some math tells me that comes down to 32,5 hours of doing vergil 3 on easy. Depending on your daily routine that can easily take weeks. To be fair the health potions are not 100% necessary but without them it's even harder and grinding the potions probably takes less time than practicing until you don't need them.
