I found a group and did it id say it was harder than a normal mode in ff14 but not quite extreme tier. We did it first try with 2 deaths not sure i did good damage but it was a decent time. Would prefer if it was all doable in overworld in future but its def doable in a group. Youtuber has a guide up for it and i didnt die lol and i am noob. Everything else for turtle is mostly painless small bit of gold sink.
