This mod adds speed berries, a type of food that makes you run way faster for 1 minute (or 5 if it's cooked). Speed berries are obtained by putting a speed berry bush in the crafting grid. Speed berry bushes generate naturally near water like sugar canes and can be farmed (if you're playing in a world you created before installing this mod, speed berry bushes will only appear in areas you haven't yet visited). Speed berries give the potion effect Speed 20, which normally can't be reached without commands or mods. They are therefore way more powerful than speed potions.
