I admit that when I played the original Demon's Souls, I cheesed Tower Knight. I basically found a spot he couldn't get me and shot arrows all day lol. When I played the Remake, I ended up doing the same thing lmao, but I definitely want to redo it. I want to win a legit way, with skill! But yes, I've cheesed bosses before. Sadly when I first played Bloodborne, my game was suffering from a memory glitch in which the bosses became idol, with very little action. I didn't know at the time what was going on, but I took advantage of it and won lol. I ended up doing that for like the first half of the game.
How about you, SW? Have you ever cheesed a boss just to win?
