💀 THE SANITY MECHANIC

Unlike traditional deckbuilders, Eldritch Deck features a dual-resource system. Your HP is your body, your Sanity is your mind. The most devastating cards — Void Blade, Necronomicon, Corruption — cost Sanity to play. Some enemies attack your mind directly. If either reaches zero, your run ends.

How far will you push before the Abyss pushes back?
