We are in the DMC3 forum dude, and there is no such thing as a Hell Vanguard in DmC anyway lol.
Also, DmC Bloody Palace is far easier than DMC3 Bloody Palace in my opinion lol.
Just a fight against Vergil version 3 (which is fun) but he does like normal difficulty damage, if you can beat the rounds of perma dted enemies before him, you can EASILY beat his ass into the ground. Now if he did DMD damage that could be a different story, but he doesn't, he hits peanuts so yea.... nice and easy battle to finish Bloody palace.
