Mostly likely you will be doing Stone Coatl with a crew. Important thing you need to know, is that the monsters with be blue to your highest CL member. So if you have a member at CL 10 and the rest are 8 to 9, the CL 10 member will see blues which the others will see yellows to greens. If all member go into the tomb at the same CL range they will all see blue. Example if you all CL 8.8 & 8.9, this will make the monsters blue to all members. It maybe easier to fight Stone Coatl & his minions with your crew at the same CL level because no member will be a real disadvantage against the monsters.
