Insane Difficulty: Deep Dungeon in Content Dilemma - Insane Difficulty

So I've reached the end of 1.3 content and decided to do the deep dungeon. I come to find out all the enemies are level 99 whereas my highest is around 52.

The thing is if I power level all my characters to 99 in order to compete in the deep dungeon then it renders all the battes in murond trivial. Are the end boss battles scaled in content or are they at a set level like any other story battle?

I guess it's time to start the real game?

The levels in the endgame in Content are also set. You might as well keep a save outside the end sequence and finish the story, then come out to try going to the Deep Dungeon, but that'd require you to level to 99 as you mentioned.

At that point, yeah, I'd advise you to start a regular run of 1.3.

I think the DD in content is the exact same as it was in normal 1.306. So yeah, if you are thinking about doing a DD run, you might as well just play normal 1.3.
