The part people ask about first· III
Dice and rolls
You roll your own dice, you see the number first, and the Dungeon Master cannot change it afterwards.

Can the AI Dungeon Master cheat on your dice rolls?
No. Every die is generated on your own device by its cryptographic random number generator, and the outcome is worked out and recorded before the Dungeon Master writes a single word. It never sees the number before you do and has no way to change it afterwards. A miss stays missed.
What a roll looks like
When the story needs a die, a card appears with the roll already worked out: what you are rolling, against what, why, and every modifier that applies. You tap it. The dice tumble and settle on your screen, and only then does the result go anywhere.
The crown's scream claws at your mind. Hold on to yourself.
Roll: 1d20+2
d20[12] +2 = 14
14
SUCCESSWhere the numbers beside the die come from
The modifier is not a guess. It is assembled from your sheet and from whatever is currently true about your character, and every part of it names its source.
| Source | What it adds |
|---|---|
| Bless | +1d4 to attack rolls and saving throws |
| Bane | −1d4 to attack rolls and saving throws |
| Guidance | +1d4 to ability checks with the chosen skill, for the duration |
| Bardic Inspiration | d6 at level 1, rising to a d12 at level 15 |
| Divine Smite | 2d8 radiant at 1st level, up to 6d8 at 5th, plus 1d8 against fiends and undead |
| Reliable Talent | A d20 below 10 counts as a 10 |
| Rage | A flat bonus, which does not double on a critical, because only dice do |
Advantage and disadvantage are rolled as they are written, two dice keeping the higher or the lower. When both apply they cancel to a flat roll, exactly as the rules say.
Your blade finds the gap in its armor. You pour everything you have into the strike. Golden fire erupts along the edge of your sword, burning through scale and sinew. The creature staggers. It does not get back up.
What stops the Dungeon Master fudging?
Three things, and none of them is a promise.
- The result is applied before the narration is written. Hit or miss, success or failure, damage taken: all of it is decided and recorded, and then the Dungeon Master describes what already happened.
- It has no tool that can rewrite a resolved roll. They were removed from what it can reach.
- It cannot accept a roll it did not deal. Typing "I rolled an 18" does nothing; only a real card counts.
“Never fudge rolls. All dice results shown transparently.”
In the middle of a fight the same rule holds in the other direction: the moment you owe a roll, the Dungeon Master stops writing and waits rather than narrating past the dice.
What we do not claim
Your dice are rolled on your device, validated server-side, and written to a permanent log. We do not claim they are tamper-proof or provably fair, because a number generated on your own machine cannot honestly be called either. What we do is check that every result is one the card could actually have produced.
So what does the Dungeon Master decide?
How hard something is, and whether the fiction earns you advantage. That is a Dungeon Master's job at any table. It picks a difficulty band from the fiction rather than reaching for the same number every time, and it is explicitly told not to: a session where every check comes back medium is a broken session.
Monsters roll too, in the open, on the same terms.
