atoll

I'm looking for a summoner that can help me with Golden Salvage. I'm trying to get my yigit crown. i have 9.000/20.000, with 3 ID cards ready to use. i"m looking to do three runs and we random to see who will take the band for each run. Some other pieces that come from this mission is i think...

Anyone know how to get this staging point through the undersea ruins? I can't seem to find a guide anywhere.
