HOW TO ACHIEVE THE UMBRAL ENDING in Lords of the Fallen (2023)

I highly recommend to do the Umbral Ending in normal game, since NG+ seems to be somehow f*cked in terms of balancing...
I had to do it in NG+ and I cannot recommend.
00:01: Step 1 - buy the Umbral Scouring Clump and enter Mother's Lull
00:52: Step 2 - talk to the non-hostile remnant to receive Damarose's Seedpod
00:55: Step 3 - kill Damarose
01:10: Step 4 - return to Mother's Lull to receive Gerlinde's Seedpod
01:15: Step 5 - kill Gerlinde
01:24 Step 6 - kill the Lightreaper and then hand over his Umbral Parasite at Molhu's Place
01:42: Step 7 - obtain Adyr's Rune either in the Abbey of the Hallowed Sisters or from the Iron Wayfarer in front of the Castle Bramis Gates (DO NOT open the gates of the castle yet!)
01:50: Step 8 - give Rune of Adyr to the remnant to receive the Withered Rune of Adyr and Melchior's Seedpod
03:32: Step 9 - use Melchior's Seedpod on Adyr
03:57: Step 10 - kill the Iron Wayfarer
04:06: Step 11 - hand over Harkyn's Parasite
04:28: Step 12 - talk to Molhu
04:46: Step 13 - use your Umbral Lamp on Pieta
04:53: Step 14 - kill Elianne the Starved
05:04: Step 15 - hand over Elianne's Umbral Parasite
05:23: Step 16 - enter Mother's Lull one final time and you're done. :)

Does this quest auto-fail if you also fail Damarose's quest by cleansing a beacon, since Damarose disappears as an NPC?
