The common armor enchantment and the common  weapon enchantment also have a chance to create the potion, as well as other consumables.

Usage
Swiftness potions grant the hero increased movement speed, identical to that of the boots of swiftness and the death cap mushroom. Swiftness lasts for twenty seconds and can be combined with the boots of swiftness and the death cap mushroom to temporarily double or triple the Speed effect.
