Exploration: Play cards to move through the mountain. Every card costs Magic. If you run out, the Void claims you.

Bonds: Use Bond cards to connect with the heirs. Reach 100 Bond to earn a Mark — essential for breaking boss shields.

Alert: Cards are noisy. When Alert hits 100%, a Guardian will find you. Use Void Shields to stay hidden.

Combat: In battle, your deck swaps to a Combat Deck. Use Lashes (free) and Strikes (magic) to fight.
