just a little walkthru hope it helps a bit.
all boss in VC cannot b put into stun so change combo where appropriate.
incase of shor-cut kill this fire boss and pick up "fire element"
in case of cannon route (longer route) all calss just has to stand right by d canonn.prison guard will b in ur AoE stun move 4 most classes.
inside cannon gate is d force archer boss.his def is low so easy to kill.
