We were playing a Zelda-based D&D game and I had happened to obtain the master sword. “I’ll fight you for it” someone in the party said. I asked how he was going to do that and he said that he was going to travel back in time just to beat me for it. He suggested that I better make a new character sheet for my alternate past self quickly to get it over with. “Are you serious?” I asked. Before I was about to start to take him up on his offer, I clarified with the DM whether or not attack multipliers stacked additively or multiplicatively. It turned out that my party member was joking.
