Blessing and weapons of light on one of the daughters platforms with touch of malice to kill ogres. Have everyone kill the knight that appears next to their platform or the opposite one. Titans that killed ogres shoot the vessel now. If the tomb ship is too close and the runner has the relic everyone should jump to the platform with the titans to protect themselves AND inform the fireteam if they couldn't kill the knight due to time or health so it can die bfore eating the lights. The runner should get to the platform asap to shoot oryx. It is not that hard as long as everyone carries out their duty well, which is a matter of practice so b patient if you are with a new fireteam. Of course if after the third or fourth try the same mistake is causing a wipe then a restrategy or another fireteam is in order. There is room for error (except a guardian down) but only if the fireteam is supportive in order to correct such error (usually missing a knight)
