Your party enters the room.
Do they walk out?
That encounter you spent an hour prepping?
It could be a cakewalk or a funeral.
Test it before your players do.
The problem
Difficulty ratings were never built
to predict what actually happens
The official difficulty system is a rough estimate. It ignores how many actions each side gets, what spells are in play, and who's actually in your party. Every DM who's trusted it has a story about the session that went sideways.
Numbers don't tell the full story
Eight goblins against four players? The book says "Easy." But eight attacks per round against four is anything but.
Your party matters
A group without a healer plays completely different than one with. The difficulty rating doesn't know who's at your table.
The labels lie
Some encounters labeled "Deadly" are a cakewalk. Some "Medium" ones end with everyone rolling new characters. You've been there.
How it works
Stop guessing. Know.
Arcanalyse doesn't use a formula. It actually plays out the fight. Both sides make smart decisions, just like real players would. The result: real odds, not rough estimates.
Set up the fight
Tell Arcanalyse who's in your party and what they're up against. Pick from hundreds of monsters or add your own.
Let it play out
Arcanalyse simulates the encounter over and over. Attacks, spells, abilities, everything. Like running the fight a thousand times in fast-forward.
See what happens
How often does the party win? How often does everyone die? How long does the fight last? Plus tips to make it easier or harder.
What you get
What you actually learn
Survival odds
Your party wins 73% of the time, with a 12% chance of a total wipe. Real numbers from simulated fights, not a rough estimate.
Round-by-round breakdown
See how the fight unfolds over time, when it tips, and which rounds get dangerous. Not just the outcome, but the full story.
Hidden dangers
Some monsters can knock out a character in a single hit. Some abilities shut someone down for multiple rounds. Arcanalyse spots these before your players find out the hard way.
Easy to adjust
Remove a monster, add another, change the setup. Run it again in seconds and see how the odds shift. Tweak until it feels right.
