The arrow above a card marks your selection. Its effect appears below. You cannot use an empty slot or a card whose energy cost you cannot pay. Select and confirm END TURN to let the enemy act.
Restarting or returning to the title during play asks for confirmation. NO is selected initially. Choose with A/D, confirm with RETURN, or cancel with SPACE.
Battles and deck
- Maximum HP is 60. Each turn restores energy to 3 and draws four cards.
- Played cards and cards remaining at the end of a turn go to the discard pile. When the draw pile empties, the discard pile becomes the draw pile.
- EXHAUST removes a card for this battle; it returns for the next battle. A resolving card cannot draw itself with its own effect.
- NEXT shows the enemy's next action, cycling through attack, defense, and heavy attack.
- SH is shield. Incoming damage uses up shield before reducing HP. Your shield expires at your next turn; enemy shield lasts until the enemy's next action.
- POISON deals damage through shield before an enemy action, then decreases by 1.
- WEAK reduces the enemy's attack by 3. VUL increases your attack by 50%, rounded down.
- STR adds attack power for the battle. ECHO doubles your next attack. THORN retaliates against the enemy's attack that turn.
- DRAW, USED, and X show the sizes of the draw, discard, and exhausted piles.
- After a victory, add one of three cards or choose REST to heal 10 HP. Either choice also heals another 4 HP. Defeat the final boss to win.

THE ORACLE is the fifth-battle boss. Its silhouette, next action, your buffs, and your hand share one screen.

Choose between strengthening your deck and healing. Cards you acquire remain available in later battles.
