As the title says, I bought about 10 potions of flame slaying (the ones you get from the badge vendor in lions arch for 1 dungeon token) I kept wondering why they were wearing off so quickly when it didn’t feel like I had spent an hour in game. It turns out the buff was going away when the potion still said it had half an hour left on it. This happened about 4 times in a row. I was using another food at the same time (half an hour duration) and they would always go off together.
