Use these guys on Ragnarok to become a force to be reckoned with. Spawn in highland east and run up along the edge until you get to the waterfall. Build there, and work your way to stone and flight. Lead the allos into a 3x3 trap one at a time, do not kill them until you are capable. Always go for the alpha. These guys are mini gigas, if you get enough of them, you can kill a low lvl wild giga with casualities, being the lowest levels. You are now safe from ground attack and put turrets up to defend against the occasional wyvern attack.
