Using Regen drinks such as Selbina Milk can make the armors soloable, provided you have enough milk and are able to dodge or absorb Aetheral Toxin, as the Armors' hits will in most cases be canceled out by the milk's Regen. It is generally advisable to solo the armors that spawn furthest from the zone's entrance, so as to not take them from players that want to fight them as a group. NOTE You can use Dream Robe +1 here to extend the Selbina Milk duration by 30 seconds.
