Remnant 2 (PS5) - Solo Apocalypse Difficulty, The Forgotten Kingdom (Part 4, Ending)

Remnant 2's second DLC focuses on the Yaesha biome and story. Players will uncover the dark past of the missing Yaesha tribe as they attempt to quell the vengeful fury of an ancient stone entity called Lydusa. Pass through the enduring remains of anguish, betrayal and disappearance that infest the once majestic ziggurats of the land, as the living stones of Lydusa wander the decaying remains of an ancient society in search of new blood.
Lydusa certainly has some very interesting mechanics that if you didn't put enough damage on your build, she will instantly kill you at the very end.
She deals chip damage throughout her entire fight, this certainly will put pressure on most non-defensive builds. You also have to fight her with the curse she put on you which will decrease armor by 15%. It's not much if you're already stacked on armor effectiveness but she will hit hard if you don't have it.
When she hits about 10% health, she will give you roughly 20 seconds before she instantly kills you with the walls. You must kill her during this time and her face will reveal her weakspot.
