Chapter 12 — The Encounter Generator

A GM tool. Tell it your table and how hard you want the fight, and it rolls you a group of foes drawn from the bestiary — no Challenge Rating math required.

Set your number of players, their level, how hard you want it, and who they’re up against, then press Roll encounter. Each foe links to its full stat block; reroll until it feels right.

• Difficulty — Easy (a warm-up) · Fair (a real fight) · Challenging (bring your tricks) · Run! (an encounter the party is meant to flee).
• Who — city guards & Guild muscle, the Warrens underworld, the Waste-Lands frontier, Callings & OCTA casters, wild beasts, the Hollow, or a mix.

How difficulty works — CR without the headache

You never have to read a Challenge Rating to use this tool, but here is what is happening behind the button.

What CR means. Every creature in the bestiary carries a Challenge Rating — a rough difficulty number. The rule of thumb: one CR-X creature is a fair solo fight for four level-X characters. A CR 3 foe is a genuine fight for four 3rd-level heroes; a CR 7 foe would flatten them. Under the hood a CR is just a bucket of XP (shown on each block, e.g. CR 1/4 (50 XP)), and it is that XP — addable across several foes — that lets the tool build a whole group into one fight.

What the tool does with it. It looks up the standard XP budget for your party — how much enemy XP a group of that size and level can take at each difficulty — fills that budget with foes that fit, and prints an honest verdict of where the fight actually lands:

• Easy — a warm-up; they will spend almost nothing.
• Fair — a real fight; expect roughly a quarter of their resources gone.
• Challenging — bring your tricks; someone may break or get scared.
• Run! — deliberately over budget: the fight the party is meant to flee, for when the world should feel bigger than they are. Its verdict usually reads Deadly or Overwhelming.

Treat the verdict as a guide, not a promise. CR is a blunt instrument, and three things bend it hard at the table:

• A lone boss is weaker than its number — four heroes get four turns to its one. (It is why the bosses here command allies and strike on reactions: that fakes the extra turns back.)
• A crowd punches up — six CR-1/8 Street Toughs throw six attacks a round, which is nastier than the arithmetic admits.
• The fiction rules everything — an ambush, the terrain, and how much the party has already burned that day matter more than any number.

So roll it, read the verdict, and adjust by feel. And because the tool only knows the premade combatants in the bestiary, its pools grow every time that roster does.
