  • Heal glossary wording restricts the wrong sidedesigner
    RULING
    The printed glossary line "a figure can only target allies unless otherwise specified" is misworded and should read that a figure cannot target enemies with a heal unless otherwise specified. A figure may therefore target itself with a ranged Heal ability. Isaac confirmed the correction directly: "Sorry for the confusion. The rule should say something like this instead."

  • Monster focus examples on page 27 omit the initiative values they depend ondesigner
    RULING
    "You are correct. In order to determine the focus in this case, the initiative values would have to be shown, and they are not. Sorry for the confusion."

  • Scenario 21, Room 3: Giant Vipers' maximum hit pointsdesigner
    RULING
    The printed special rule omits the number ("have their maximum hit points value reduced to, but gain a permanent Shield L+2"). Isaac's correction: "Reduce their hit points to 1."

  • Scenario 12: one Living Corpse spawns per destroyed pillardesigner
    RULING
    A Living Corpse spawns for each of the four pillars destroyed, not only for the first pillar on each side. Asked whether the count was 2 or 4, Isaac answered: "4 total."

DESIGNER CLARIFICATIONS6
  • The Favorite's bonus is doubled by ×2 and erased by nulldesigner
    CONTEXT
    Players assumed the Hatchet's +3 from The Favorite was added after the attack modifier card, so that ×2 would not double it and null would still leave 3 damage.
    RULING
    "The +3 would be doubled, and the null card always causes zero damage."

  • Order of operations when resolving an attackdesigner
    RULING
    "All attack bonus (like the +3 or the doubling or the effect of poison) is applied first in whatever order you want, then you apply the attack modifier, then you apply shield." Worked example given by the designer: an Attack 3 against a monster with Shield 1, using both the Favorite bonus and the Double Throw bonus, resolves as (3+3)×2 = 12, then the attack modifier (−1), then the shield (−1), for 10 damage.

  • The Favorite token moves only after the attack resolvesdesigner
    RULING
    "The token is placed on the monster after the attack is resolved, but the +3 is added during the attack."

  • Sand Devil ignores difficult terrain but not obstacles, objectives or wallsdesigner
    CONTEXT
    The Red Guard's level 5 Sand Devil is a trap rather than a summon, and the card does not state how it interacts with terrain when moved.
    RULING
    "One bit of clarification that is not on the card: it is unaffected by difficult terrain but can't be moved through obstacles or objectives (or walls, of course)."

  • A spawned monster does not enter the hex it appears indesigner
    CONTEXT
    Players asked whether the Red Guard's Flame Shroud, which triggers on a monster entering an adjacent hex, fires when a monster spawns adjacent to him.
    RULING
    "A spawned monster doesn't technically enter the hex it in which it is spawned. Entering a hex is specifically tied to movement, which it is not doing." A spawn is treated exactly as setup during the reveal of a room, so entry-triggered effects do not fire.

  • Each hex inside a purple border is its own difficult terrain hexpublishercommunity high-engagement
    CONTEXT
    Scenario 3's difficult terrain is drawn without internal hex lines, leading players to treat the whole purple outline as a single space for movement and for ranged attack range.
    RULING
    "Any hex that has a purple border takes 2 movement to get into, and 2 movement to move through. For example in scenario 3, if you were to be in any hex inside the purple border it would take 2 movement per step. 2, 4, 6 etc."

Q&A3
  • Can you grant an action to a character who is long resting?community high-engagementlinked official source
    QUESTION
    A character has declared a long rest for the round. Can an ally still grant them an action or an attack that round?
    ANSWER
    Yes. A long-resting character still has a turn and can be granted actions and attacks, and can still use items. Per the official Gloomhaven FAQ, the restrictions are elsewhere: you cannot grant actions at all to a stunned character, and cannot grant attack abilities to a disarmed character.

  • Are a character's abilities suspended while long resting?community high-engagement
    QUESTION
    During a long rest, do active and passive abilities such as the Hatchet's Overwatch or the Red Guard's Shield Spikes stop working, and does existing Shield still apply?
    ANSWER
    No, nothing is suspended. All active and passive abilities remain in effect during a long rest, any existing Shield still applies, and items can still be used. The only restriction is that you play no new cards that round.

  • Can you perform part of a loss action without losing the card?community high-engagement
    QUESTION
    On a card whose bottom action reads "Move 4" followed by a separated persistent effect, can you perform only the Move 4 and skip the rest, keeping the card out of the lost pile?
    ANSWER
    No. There are no loss abilities, only loss actions — performing any ability within a loss action sends the whole card to the lost pile. The only way to avoid losing the card is to use the card's generic Move 2 or Attack 2 instead.

EDGE CASES2
  • Poison applied by an attack does not boost that same attackcommunity high-engagement
    SITUATION
    A viper with Attack 1 attacks a character who is not yet poisoned, and the attack itself inflicts Poison.
    RULING
    The attack applies the condition but gains no benefit from it. All attack effects, including conditions, are resolved and assigned after the attack, so the target takes 1 damage and becomes poisoned rather than taking the poison bonus on the triggering attack.

  • "Never leave a hex adjacent to a monster" battle goalcommunity high-engagement
    SITUATION
    A character standing adjacent to a monster wants to reposition to another hex that is also adjacent to that same monster, or to leave and re-enter the original hex within the same turn.
    RULING
    Both fail the goal. Exiting the hex is the trigger, regardless of where you end up: you may not reposition into another valid adjacent hex, and you may not leave and re-enter the hex by the end of the turn. You are locked in place until the monster is dead — that difficulty is the point of the goal.

HOW MIRA KNOWS

Not an AI guessing rules. A curated archive.

Every answer Mira gives is grounded in an official rulebook — not in what a language model thinks the rules probably say. Our team reads, structures, and curates each game's rulebook before Mira can answer a single question about it.

An opponent's settlement blocks your road network — your road cannot be built through or past an occupied intersection.

Catan — Roads & Building, p. 7

At the end of each round, the player with the most of the goal trait scores points equal to their amount; the player with the second most scores fewer.

Wingspan — End of Round, p. 11

Null cards deal 0 damage regardless of base value or any bonuses applied.
