Roll your hero (ATK, DEF, HP, SPD) — 6 + 1d4 four times, assign each. Rebalance up to 4 points, then draft 1 of 3 starting gear pieces.
Each turn: roll movement (1d6 + boots bonus), walk the dungeon, open chests, fight mobs, play cards.
Combat: highest SPD strikes first. Damage = max(1, ATK + d6 − opponent DEF). Repeat until one side falls or flees.
Three floors deep, each with mobs and a boss. The final boss on Floor 3 is one of three, picked randomly at game start.
Die and you lose floor-many items (Vaulted slots are safe). You respawn at full HP, gear you have left.
You can attack other heroes too — Ambush, Assassinate, steal their gear. Whoever lands the killing blow on the final boss wins.
Survival Mode: endless floors (boss every 3rd), no wells, no heal on descending — potions only. From your 4th turn on a floor the ceiling comes down: 1, 2, 3… damage each turn until you find the stairs. Death is final. Score = floors cleared.
