You're welcome bud!
Well, I haven't exactly finished it, I did manage to finish the 3rd Pantheon though, I also made it to Pure Vessel on the 4th Pantheon
(for some reason it felt a bit easier than the 3rd one, it just took longer cause all the bosses are such damage sponges xD) but so far I haven't beaten him yet.
I've tried a bunch of times in Hall of Gods and... HE'S SO BLOODY FAST! He honestly feels even more difficult than NKG.
And on that note, quite honsetly, I just despise the double damage some bosses have, sorta makes all the health upgrades you got kinda pointless... oh well, but I guess that's just how itis xD
I might try again some time against PV and the 4th P, but the Pantheon of Hallownest can suck a bunch of dicks, and all the bosses on ascended and radiant can jump down a bottomless pit for all I care.
Overall it really feels like this DLC was specifically made for the absolute masochists of the community... good for them I guess xD
Have you finished it, though?
