So you’ve decided you want to take a go at writing monster cards? This can be a stressful endeavor. Too much in one direction, and you’ve killed all the people you intended to entertain. Too much in the other direction and the fight was largely a joke.
Here are a few simple rules.
Follow the 1 damage for 10 body rule
Generally a really easy want to create monster cards is with the 1/10 rule. For every one damage your monster swings, it should have 10 body (or armor if you’re willing to rep out npcs in heavy armor). This seems to be a great easy rule to follow. Your baddies can last long enough to hit a wall with a line of players and still get some damage in. The scale on these monsters body gets ahead of pcs body pretty quickly but, generally your npc ratio isn’t 1:1. So that extra body helps keep them entertaining players.
