The world of Dragon Quest 3 Remake is filled with a constant barrage of monsters and enemies, so it's good to have the best possible weapons at all times. Once you enter Alefgard in the second half of the game, and reach the town of Cantlin, you'll discover a well-hidden side quest that will allow you to stop looking for weapons for the rest of the game. This is because you'll be able to forge the Sword of Kings.
