If you are a spirit sader, do not think about trying to obtain CoBB. Boiling trace is a more suitable cross. CoBB is more suitable for vitality sader because of the intense strength and physical attack settings. The settings for WB is meh at best. Also specific recipes aren't limited to certain dungeons. They're limited to specific dungeon ranges. The guy I got this CoBB from got the recipe from gabe through otherverse dark side.
