Golden Sun: DD - Crossbone Isle

I think I've done fairly well... got all 72 Djinn, got all but two summons, and now I'm trying to get Charon and Iris before I fight the final boss. But does anyone know where Crossbone Isle is? Because I can't seem to find it anywhere. Any help would be appreciated.

Nevermind. If anyone wants to know, you have to beat the game first...

 

I'm telling you, the boss of Crossbone Isle is a freaking MONSTER.
He makes the last boss look like a fluffy rabbit, THAT'S how hard it is

 

can you beat it easily with all your players lvls maxed

 

You can't beat this boss 'easily', but it is possible, after a long and gruelling battle

 

woah haha gues i have to stock up everyone with herbs what does the boss look like

 

tbh no boss of GS to my experience is nintendo hard, its just difficult and it possible to ebat any boss if you prepare yourself have good equipment and dont go around like a moron...

 

well said

 

forget herbs, get vials instead

 

agreed... i dont know about you guyz but to be honest. i've defeated dullahan in just 3-4 turns... Just put all your djinn in standby then summon all the way... Mattew, Tyrell, Himi and Eoleo on the attack group... Summon the fire monster (the thingy with the missiles and massive nuclear bomb). All 4 of them then switch one by one then summon again (thor, boreas etc) by the time you know it dullahan will be eating dust!!! ;D ;D ;D

GSD is a very nice game, however CAMELOT should try and put some challenge to the next franchise it would be making. More boss fights, challenging enemies, more weapons?. I believe this game has just 5 boss fights? well at least a point in the game that made me feel that im about to fight a strong monster (the sand prince, the ice queen, sludge, mountain roc, and the final boss).. Well i barely thought it was already the final boss... It's a great game but sadly i think it's a game that well, is just very linear that you barely have work hard, grind for experience, explore for secrets or even prepare for boss fights... Sad to say but very little excitement? Or maybe im just expecting too much from a great Title i haven't heard for so long?

 

to bad for me... i cant find the 8 dijin and my lv is still 50... but i defeated dullah... only got irish THAT i cant summon becose i only have 8 fire dijin in my team.... u can get to crossbone island after beatingthe game...
go to yamata city talk to a man near the entrance...he'll come with you and tell you where's crossbone island...
