Transmigration Mission for myself is BROKEN. I completed it once and now when I attempt it againthe Boss behind the first door no longer spawns so I'm standing on top of the funky ground and TAB says I'm where I'm supposed to be... NO BOSS... So I transition to next mission window (UNKNOWN) which puts me back on same path jumping to reach the inner stomach of the alien aka restarts the mission from start.... NEVER ENDING LOOP.... but each time the Boss behind the Icon of Darkness ran for the freaking hills and the next room might as well say Stop Playing Destiny 2 cuz your F_C_ED. Not like most games where you can drop quest and pick it up again. So............... P.S. I'm not quitting and I do suggest Destiny 2 to my friends. 2nd Page allows LAUNCH but it just takes you back to the beginning of the mission. https://www.ign.com/wikis/destiny-2/Transmigration Two Icons of Darkness will be needed. Got the first to be able to stand on the ground that points to the floor. Nothing inside to get 2nd icon from. "Inside, you’ll need to jump up to reach the higher floors, and once you’re outside again, you’ll find the Resonating Grim, a bird-like enemy, before using the platforms to cross the gap and proceed. At the other end, you’ll find more Grims and Taken; once you defeat them all, you’ll find the Icon of Darkness. Just like with the Icon of Light, grab the Icon and destroy the Grims, before using it to open the barrier. "
