So, I’m fighting him with Melee Athena, no problem. But, almost every time I Blood Rush him, I get stuck in his FACE. Finally, I got stuck and got shot down, and it was impossible for me to get a second wind. I wouldn’t be too pissed off if I got to resume the fight with him still in his Empyrean form, but no, I have to START ALL OVER with his human form. This glitch needs to be fixed ASAP.
P.S. This glitch may occur during the main quest, but most of that time I forgot to Blood Rush Empyrean Sentinel, so I don’t know.
