THE EXPLORATION

Every tile is
a decision.

    Follow open paths one tile at a time. Uncover chests, fountains, traders, and enemies through the fog.

  2. 02
    Commit to the encounter.

    Step onto an enemy tile and movement locks until the fight is over. Check your frontline before you go.

  3. 03
    Get the loot home.

    Find the exit and meet any listed requirement. Confirm Exit keeps your backpack; defeat or forfeit loses it.

Tide SlimeENEMY BOARD

Five cards to choose fromSAME EXAMPLE BATTLE
The five-card hand: Basic Attack, Healing Word, Water Symbiosis, Pilgrimage, and Touch of Grace, with the owning servants shown below.

Read the other board, too.

THE ENEMY HAS A DECK, TOO.

Plan around what’s coming.

The Tide Slime preview above has Bubble Melody queued at 3 and Basic Attack at 1. Read enemy effects and countdowns before committing your next card.
