Use Sleep to sleep non NM Drake, focus on the NM Amaljaa (He can Shadowsear) then the NM Drake. PGL try to stay on the side of the Drake, neither in front or behind, only move behind for Blindside II then move back to side. The FNM is supposed to be for Light Party +, meaning minimum 4 people. If you are going to do it low-manned, you will need to be very effective skill-wise and equipment-wise.
