How to reach Berserker Gravestone in The Sinkholes
This guide shows how to get to the Berserker Gravestone in The Sinkholes area of the Vanaheim Region in God of War Ragnarok.
Note: To get this, you must flood the crater by completing Return of the River favor.
The gravestone is at the location shown in the picture below. As you reach the location, you will see a dragon sitting on a pillar. Destroy the pillar the dragon is sitting on with your spear. Then destroy the second pillar the dragon sits on. This will start The Burning Skies Favor.
As you destroy the pillars the dragon sits on, the dragon will fly away. Then open the gate on the south side of the area by pulling the chain near it as shown in the picture below.
Now go back to the dock near the sinkholes mystic gateway and hop on the boat. Row the boat back to the area where you destroyed the pillars the dragon was sitting on. Dock the boat as shown in the second picture below and climb up the stairs on the right side to reach the platform the dragon was on to find the gravestone. Interact with the gravestone and defeat Haklangr The Bearded to get Chaos Flame weapon upgrade.
