Die in the Dungeon

Die in the Dungeon swaps a deck-builder's usual cards for a pool of dice, and the twist is that each die's face value dictates exactly what it does that turn, so a roll isn't just random flavor, it's the actual decision-making layer the whole run is built around.

Because dice are placed rather than played like cards, planning where a high-value roll goes before committing to it matters more than reacting die by die, a strong roll wasted on a weak slot is effectively lost value for that turn. Upgrading dice to add reliable faces rather than swinging for rare high-value ones tends to produce more consistent runs, since a deck full of unpredictable dice can just as easily collapse a run as carry it. The Binding of Isaac covers similar dungeon-roguelike ground built around item synergies instead of dice.
