Is Erlang the hardest boss?

Been playing through recently and just finished the game today (loved it)

Honestly not trying to brag but for the most part I found it easier than I was expecting… that is until Erlang…

I’ve come so close so many times but he is honestly sucking the fun out of the game with how ridiculous he is….

Half my spells/abilities are completely useless on him, he just sidesteps my heavy attacks and don’t even get me started on his god damn shield…

Anyway I know I can beat him but… is this the worst of it? I really don’t want to bother if there’s just going to be an even more broken boss around the corner…

I really want to go for 100% and it would be a shame to quit now but if there’s worse than this to come I don’t know…

EDIT: after sleeping on it I tried again today, beat him on my second try, a lot of your tips helped a ton so thanks guys!!

Now to get everything I missed before NG+ baby!!!
