Cannot beat Dragons (The Formless, Fangscorcher) once they sit on the ledge
During the dragon fight, once the dragon (e.g. The Formless, Fangscorcher) sit on the ledge they become invincible and they do not fly down.
Once the dragon sit on the ledge they keep on firing at me and I can only damage them up to 65%, afterwards they become invincible. Also, they do not fly down, they sit on the ledge, and just hit me in loop.
Unfortunately, I cannot now progress in my game as it is a show-stopping issue. I tried to stagger them, but regardless they always fly to the ledge when they health is around 69%.
