Thorough exploration is essential
If you've played 2018 God of War, you are probably already aware of this rule. Thorough exploration is essential. There's something useful to find almost anywhere. Most often, you'll come across silver, the game's main currency. In addition, you will be able to extract more raw materials, find weapons, or artifacts. All this will boost the development of Kratos' inventory, which in this game determines the character level.
The character level is a good indicator of what kind of attitude you should take when approaching various opponents. The weaker enemies are highlighted in green, and those equal to your level in yellow. The opponents one level stronger than you are orange. The purple ones are two levels above, and those marked in red are mostly able to kill Kratos in one hit. Although these enemies mostly appear later in the game. Nevertheless, it's worth taking good care of equipment upgrades.
But that's not the only reason that rewards careful exploration. God of War Ragnarok puts a lot of emphasis on narration. The game world contains many elements that enhance it. The artifacts mentioned above are just one of them. In addition, Odin's ravens and poems return in this part.
