King's Grave contains 2 Collectible Locations in God of War Ragnarok. Those collectibles are listed down below.
Berserker Gravestones: 1
Relics: 1 (not tracked in region overview)
Berserker Gravestone + Relic: Hilt of Skofnung[]
This Berserker Gravestone is only active after you have finished ALL other 12 Berserker Gravestones. You should do 100% completion in all other regions first, then return here and the last Berserker gravestone in King's Grave will be active. It spawns King Hrólf Kraki, one of the hardest bosses in the game. Defeating him unlocks gold trophy “Grave Mistake”. You should be Gear Level 9, meaning you have fully upgrade every piece of gear you have equipped. Also make sure you have a Resurrection Stone equipped, can be bought from the blacksmith under Special Items. Put the game on the lowest difficulty “Give Me Story”. Also go to Settings > Accessibility > Combat > Miniboss Checkpoints = ON. This creates a checkpoint halfway through the fight and if you die you respawn with full health, this makes the fight much easier. The spear works best against him, it attacks quickly and makes it easy to dodge because you aren't locked into your attack activations for long.
