When wearing the Achto or the normal Primeval armour, or a combination of the two, there is a 2% chance per piece that all of your Defence abilities will have their cooldowns reset, as long as at least three of the set pieces are worn. When this happens, there is a 1 minute cooldown before they can be reset again. If you die in the Wilderness with the Achto Primeval robe legs, it will drop 9,600,000 coins instead of the item.
