Open world boss. Therefore you are not limited to creatures so let loose. Also a imprinted giga with atleast 10 mutations is the only thing that solos these guys not just one that is a dirty lie from people who think they are Chad’s a standard imprinted giga needs to be atleast (and yes this is true) lvl 600 to beat hati and another to beat skoll this is while dismount I’m sure if you cheese the bosses using the arena I’m sure it possible but you will lose that giga if you use just one. Also shadowmanes you need atleast 10-15 or you can wish them farewell. Your best bet is about 2-3 reapers as their natural armor is absolutely insane not to mention the hit hard then a wild giga when wild and hit harder then non-bred tamed gigas. Only things do the fight at night to get the natural armor reapers have as this does not work during the day
