I'm trying to make a CR 6 kobold for my game. The rules for monster advancement, NPC advancement, etc can be very confusing. Simply speaking, if I take the base stats for a kobold (warrior 1) what changes do I need to make to get him to CR 6? (I plan on keeping him straight fighter type.)
Kobold fighter 7 is CR 6 assuming it has NPC wealth by level (WBL). Good luck!
Kobolds are a featured 0 HD race in ARG. Give his 7 levels of fighter and done.
Alternatively, as Kobolds with NPC class levels have a -3 rather than a -2 to their CR calculation, you could go for Warrior 9.
