Dragon Crystal

Dragon Crystal is an RPG with roguelike elements, released in 1990 for the Master System, and in 1992 for the Game Gear. 
 
The player starts the game in a maze-like level covered by fog of war, which he must navigate to find the warp gate to the next floor. There are thirty floors in total, all randomly generated. Weapons, armour, money, potions, food and enemies are also randomly placed. Combat is turn-based, initiated by moving your player into an enemy.
