In Minecraft, we have cocoa beans, but not coffee beans. If we add coffee beans, I'm thinking they would grow on jungle trees, as well as cocoa beans. you would use them on a brewing stand to make coffee, which would give the player speed 1 and haste 1 while in effect. after in wears off, the player would have mining fatigue 1 and weakness 1 for a short time afterward. bees would also land on the coffee beans, like with flowers, except afterward, they have speed 1. also, adding sugar to coffee in a brewing stand would increase the speed by 1.
The Meaning of Life, the Universe, and Everything.
Bit of an iffy one. While having access to haste without a beacon sounds exciting, I feel like that would take away some of the value of beacons and the whole adventure that is getting one. If nothing, though, at least it'd teach kids about how an addiction forms!
