Dear Matteo, maybe I missed some rules, just where could I figure out the enemies attributes?
Hi! The enemies haven't stats - it's a game a little bit different than "the most famous fantasy game." The system is based on Blades in the Dark - and tags and short descriptions describe the NPCs.
As a rule of thumb, if an enemy is weak, full success is enough to defeat it. If the enemy is strong, you can create a clock.
