Boots of Quickness and Jade Armor give the same benefit as the spell. Heroic Quickness, W9 blessing, and possibly the Champion's Trident (Death match winner's price) have different effect, so they stack with each other AND with the spell/Boots of Quickness/Jade Armor. However, I'm not sure of the Trident; it might have been the same as the spell.
