Are bosses this unbalanced all the time?

honestly, i want to punch you

Elius is not hard, but annoying, at least for weapon users.
Calvus, on the other hand, both hard and annoying.
So everything is relative. If you manage(And I believe you can) to defeat Elius, then when you face, you’ll remember him and say “Oh god, I wish I never said Elius was hard!”

skill issue

Revon was ez (bugged out and wouldnt move)
