Devil May Cry 4 HELP PLEASEEE

hey

i am on the 8th mission of DMC4 and iwas just checking out the help for the boss fight for credo and realized that nero in the video online had a much bigger health, a shotgon instead of handguns and a huge devil bar.

i have orbs and souls but idont know how to upgrade my character

how can i do it?

please help ASAP

all you have to do is buy the blue and purple orbs .. blue orbs give u an extra health bar and purple orbs give you an extra devil trigger bar .. you can get blue orb fragments durin the game .. u'll need 4 blue orb fragments to get a blue orb .. i hope this helps ..
