Have tried many times, and finally figured how to deal with it. Basically you have like around 1 minute to lure Baphomet to the top altar, activate the seal and kill it. After that it became invincible. The timing for Inspiration is important. You want to make sure you are all buffed up exactly at the time when the ancient hero tell you to activate the main altar. I think starting inspiration when the ancient hero tell you don't be discouraged is a good timing. I am glad this time Shield Spell doesn't mess up with me.
I am using a gtb but that's not necessary. I think a wind armor is enough.
First time trying to make a video, and I apologize for the terrible quality. Thank you all for having given me so much advice. Hope you enjoy it.
P.S. Anyone know how to insert the video directly in the post, not just a youtube link, so people don't have to click on it to watch the video.
