You could give the weapon limited uses . In Baroque , the player gets a gun the Angelic Rifle at the beginning of the game that kills anything in one hit , but it only has 5 bullets . The game is a roguelike dungeon crawler without permadeath though , so if you leave the dungeon or die , you get the 5 bullets back , but basically the ammo is so limited that you ' ll just want to save it for when you ' re in a pinch . I think that sounds like a better idea give the player a powerful but limited tool rather than an unlimited one that you have to try to discourage them from using , because , as others have already pointed out , players will quite often do what makes the game easier , even if it ' s less interesting to do so . That ' s why many players grind in RPGs even if it bores themit ' s a simple , surefire way to make the game easier to get through .
