How to pass the final level of Devil May Cry 3

I will give you the simplest method, 1. Bring enough blood-replenishing and magic-replenishing props (5 of each is enough) 2. Use the liar style to wander around Brother Ding, like the brother on the first floor said Like that, if there is a flaw in his move, if you see the opportunity, you can kill him, and you can hit him three or four times at least! 3. If he turns into a demon, you should also change, and fight him head-on, and he will soon be able to do it. Returning to the normal state, if he keeps hiding, it will take a long time for him to transform into a demon! If the blood and magic power are not enough, make up for it, don't be a pity!

Playing like this may make the masters laugh, but I remember when I first played I got stuck here, and ended up living so shamelessly!
