About

D20 Descent

Features
Read full description

D20 Descent is a turn-based fantasy dungeon crawler built around one simple idea: every step rolls fate. Move one square at a time through randomly generated rooms, halls, doors, and shadows. Each unexplored tile rolls a D20 event and a magnitude die. You may find silence, treasure, traps, monsters, rare rewards, or the stairway deeper into the dark. Every run is a push-your-luck descent. Fight when you must, flee when you can, spend gold wisely, and decide whether one more room is worth the risk. Features: Dice-driven exploration: every new square rolls a D20 event and magnitude roll Procedural dungeon floors with rooms, halls, doors, fog of war, and hidden danger Turn-based combat with Attack, Heavy Attack, Potion, and Flee choices Weapons, armor, heartstones, potions, treasure, traps, and rare rewards Boss gates every five floors A final victory goal: defeat Charon on floor 30 Endless descent mode after victory Peddler’s Camp, where gold can buy potions, healing, and max HP Legacy shards that carry progress between runs through permanent boons Offline single-player play D20 Descent is built for quick dungeon runs, risky decisions, and that dangerous feeling of wanting to take just one more step.
