I'm looking to create a suitably powerful NPC for a Deathwatch Game but using the Black Crusade character generation system (purely because it's an amasing system).
The figure is a Chaos Champion and needs to be on par as a character with Rank 5 Deathwatch characters. The problem is though, that Deathwatch Experience for a Rank 5 character is 30,000 or greater. Additionally advances are often more expensive and more limited for those in DW over BC which has them fairly cheap. If I gave a chaos marine 25,000 XP to spend and asked them to run through the system in BC we'd have someone able to smack seven bells out of daemon princes in their sleep.
What then, would you say from experience is a suitable amount of experience to aim for which is roughly comparable to the higher numbers in other books?
