I got this idea for a tankard cosmetic that turns your mug o' grog into a nice hot cup o' joe. Perhaps it could have a Rare logo on it, or it could have text that reads "world's best pirate" or something like that on the front. For a splash of character, when you're drunk and play an instrument with the mug equipped, instead of making your music slurred and out of tune, the caffeine would kick in and it'd make it up-tempo for faster and more energetic music.
