Put all your characters on follow, attack 1 of the two mobs, when it's nearing 90% be ready to run, the moment you see the icon appear on the effects of the mob start running away. KEEP running until you get the 5 stack curse. At that point the dmg you will be receiving is 'locked in' so stop running, let your group catch up and healers refresh their wards and such, take the damage which should be minimal at that point and you'll be near the ramp going up. Target the other mob, get behind them (eg they are on ramp, you are closer to spawn spot), get him to 90%, run the other direction when stoneskin effect appears on mob, stop again the moment the 5 stack curse lands on you. You'll be over near spawn point, wait for other mob to get near you, then go around to their back again (now you'll be closer to ramp and they'll be back on spawn point). Get him down to 70%, rinse, repeat, 70% on other, 50%, 50%, 30%,30%, 10%, 10%, then kill.
That doesn't work for me....most are dead (crew) trying to catch up. TY for trying to help
