Pick a role, pick a tier, get a stat block that sits inside the SRD benchmarks. Every number stays editable, and it tells you when you have wandered off.
The role sets the shape of the stat block and what it costs in Battle Points.
Tier follows party level, and it drives every benchmark below.
Motives and Tactics are verbs. They tell you how it behaves when you are not sure what it would do. The suggestions are the real ones from the SRD's example adversaries, sorted by role.
Suggested values already include the role adjustment. Push them around freely, the range under each one is guidance and not a wall.
Filtered to this role, with the universal ones underneath. Click to add. Everything here is Passive, Action or Reaction, and anything you write yourself has to pick one too.
Kept in this browser only. Clearing site data clears the lot.
Click anything above to type over it. Dotted underlines and tags cycle through their options.
Battle Points are 3 per PC plus 2. This one costs 2.
