First this beast is not that hard to kill you can kill it solo with max equipment but if you have no the gut to grind that much get a buff dono (the dono that can buff,boost your tames). Then get some good damage dealers hp can be compromised cause the buff dono will buff your tames hp, then you handle the baby's (minions) of the big hell of that australia spider, so your tames can kill it .. that's it if you are a pro your tames will not die and yes for each difficult you can increase amount of tames I suggest take rexs 1 yuti for buff or if no rex take some hybrid thailaculeo
