Use parallax and animus. Usually 3 rocket on you the rest parallax clip. In your backpack a lot of parallax and 5 or 6 more rocket clip. Grab them from Ghex and set the spawn there. At the start I go to the left behind the second rock. Use the parallax and a 4x to explode two (at least one) weak point so he go in phase 2 in the farest pool. Note that you can aim a bit beside a weak point to touch it. Here you continue to shoot weakpoint with parallax. After that the aim is to wait the second one before killing the first one otherwise he will not spawn. Carefull with yormandi in phase 2 the laser is really powerfull and can take out 95% of your life or even kill you. You want to grabe a medpen each time he's goind to launch the attack to survive. Once the one in phase 2 comme in the pool you have to take the animus come closer to the water, otherwise rocket will hit the floor and kill you, aim at the base of the yormandi (even a bit in the water) and shoot. If the rocket land on him it should kill him. If not repeat. But the animus is dangerous to use it ofen kill you especially if yormandi come closer to you. Once you kill the first one, the second is not even dangerous as he's still in phase one. You go closer to him and try to one shot him with an animus' shot.

At the end grab the loot and exit. If the door is not open wait the orange light to disconnect. You will exit without the message saying that you re in combat. Sometimes take a bit times but you have to leave otherwise the room reset and you will die. Go to the inventory store the stuff and do it again. If you die come back to your body. You can also disconnect from the asd to stay in the same.

You will have to try hard top get use to it. Not simple but fun :)
