God of War Ragnarok is teeming with optional objectives that span across multiple realms, but one of the earliest you’re likely to come across is a quest (known as a Favor here) that tasks you with seeking out Draugr Holes. Each of these spawns a boss called The Hateful that you must destroy to close the hole, and you’ll receive a Chaos Spark for each one you defeat. When you’ve closed all six holes, you’ll combine the Chaos Sparks into a Chaos Flame, which can be used to upgrade your Blades of Chaos.
