Once you reach Chapter 4 of the Season Journey during The Season of Blood, things begin to get a little more difficult but the rewards are worth it.
You will most likely be Level 50 or higher by the time you start taking on the objectives in Chapter 4 and will need to stick around World Tier 3 to complete most of them.
This will mostly have you focusing on Nightmare Dungeons as well as exploring the Blood Harvest zones to take on tougher enemies and strengthen your character.
