Is great jaggi hard

A little. If you don´t have good armor, he´s gonna kill you. But since he´s the first boss, he´s fairly easy. After the first tries, he should be like a Kelbi to you :)

I agree with the guy above me. Once you take on two or three it really isn't that hard. On multi-player arena however is another thing entirely. You should use your equipment. Also one of you distract the regular Jaggi while the other takes on the big boss. You might be asking your self,"Well why on Earth would you do that? It's would be like double damage!" Well..... that is not entirely true, yes you do hit him more, but you also hit each other. So not only are you accidentally hitting each other, but you have a 2 ton giant that is all teeth and attitude, not to mention the other Jaggi. Also it may take a little while to get completely synchronized. By the way if you can kill the Great Jaggi multiple times then you get multiple coins which means A LOT of money. Good luck! :)
