That being said I still believe his items are far too strong, no matter how difficult the fight is.Boss difficulty is a subjective matter, but I do agree with analysis here, personally. Duke Fishron is a completely optional boss that can provide weapons that prove very effective against the Lunatic Cultist and the Pillars. If you don't wish to fight it, you don't have to. If you want to fight it, you better be up to the task.
True. As a mobile player, I deem him with the title of "Final boss of 1.2", Ocram is weak compared to this beastI think it's because they didn't want people new to hardmode to kill him without truly earning it. Also, he was the final boss when he came out.
