Divide them by 5. They are basically the characteristic rolls from other BRP-based games. Converting NPCs from CoC7e is just as a no-brainer as from any other BRP-based game. Monsters on the other hand...
Alas they had to introduce a separate sub-system for monsters, without any guidance for creating or converting them. Its terminology is nebulous (where do NPCs end and monsters begin?), its mechanics are confusing (half the FAQ is about how parrying, blocking, tests, conditions work for monsters), and goes against one of the best features of the BRP family: that every creature is described using the same terminology and follows the same mechanics. Even the simplification of NPC stat blocks backfired, because after the beta feedback they had to introduce a bunch of rules of thumbs for handling untrained skills and attributes for them, which are all over the place in the rulebook...
Make no mistake, I love Dragonbane and I know the rules by heart at this point. But it could have been a cleaner and tighter game if they resisted introducing their Year Zero Engine-isms into the system and leaned closer to the original BRP design principles. But enough ranting, I have a Duck Tower to convert from RuneQuest to Dragonbane...
