Magician(1990)

Magician is a 2D, side-scrolling action RPG. As Paul, you must travel through towns, have conversations with non-player characters, acquire and manage inventory (food, water, weapons, potions, etc.), learn magic spells, fight battles, and solve puzzles. Your ultimate goal: collect each of the four elemental vials -- earth, air, fire, and water -- and combine them to create the Ultimate Potion. Only then can you hope to vanquish the evil wizard Abadon!
