During the game

Using the Arbiter

Describe the setup in text or dictation, or attach photos.

01

Resolve a fight

Name the Attacker and Defender. Include their Items, Enchantments, Damage, Counters, Boosts and statuses, and which cards are Exhausted. Give the Defender's Location.

Use the Rule Masters Arbiter. Fat Dragon (1 Damage, Equipped with Very Large Cake) Attacks Cat Knight (Enchanted with Holy Light, Boosted with 1 Runestone) in the Castle. All cards were Ready before the Attack. No other effects or Counters.
02

Raise an Objection

Say “Objection!” and describe the proposed effect, how it's being made, and its cost. Leave out arguments and counter-offers.

Use the Rule Masters Arbiter. Objection! My opponent is trying to Invoke Fireball and spend 1 Runestone to Destroy all three of my Units in the Circus.
03

Ask about a rule

The Arbiter can explain card actions, costs and turn order.

Use the Rule Masters Arbiter. What's the difference between Invoking a card and Binding it?

Combat photos

Photograph the full fight, or take one photo per side. Keep each fighter's attachments and markers together. State who is Attacking.

  • Coins: Seals. Place them on the cards they're Binding.
  • Beads: Runestone enhancements. Say which are Combat Boosts.
  • Red cubes: Damage. Explain other Counters.

For photo-only fights, the Arbiter asks you to confirm the setup before ruling. Correct any errors.

Common questions

Can we resolve Combat ourselves?

Yes, if both players agree. If either player asks for the Arbiter, it decides.

What if it reads a card or marker wrong?

Correct it before applying the result. A ruling stands unless both players agree it got a fact wrong.

Do I need to upload the rules?

No. The plugin includes the rules and card lists.
