So the shade you fight at the end, basically has such an obscure, almost nonexistent telegraph for his uppercut/heavy swing knockback attack. The glow effects for the uppercut charge up attack are pretty much obscured, if you have any spell with particle effects like lightning you will easily miss it.
So you're gonna be flying around from getting an uppercut to the face out of nowhere on top of losing over half your health at armor cap. I ate two out of the blue heavy swings from him thanks to my Storm Astronach obscuring all of it.
And don't try to dodge roll out of the cone. Stay on the center of it with the boss because dodge roll is worthless against AoE effects and you will eat a whopping 1.4k damage from the ice cone if you try to dodge roll out of it.
The dodge roll in this game is so weak...
