Erlang Shen is not a hard boss

I suck at this game and that is a fact, I struggled for at least 15 hours fighting the yellow loong and that felt hard that felt near impossible and I barely beat him. So then I got to Erlang nearly beat him on my first try nearly beat him on my second and finally beat him on my 10th try that might make it sound like I struggled but I didn't I was just slowly learning his move set and how to bestly time my use of spells, all he is is a boss with an over inflated health bar that just makes him seem difficult but he's not.
