Soul speed potion

A potion that would give you soul speed effect for a short period of time for when you don't want/cant get an extra enchantment on your maxed out netherite boots. Perhaps make a new sort of mushroom, like a soiled mushroom, that is the ingredient for the new potion. You could make it from a speed potion. This would be cool if you need to get through the nether but you didn't need to be there very long.
