The Rune Slayer Rune Key is required to unlock the Tundra. But how do you get the Rune Key? Once you get to the Tundra in Rune Slayer, you might want to find out where you can find the bosses – our Tundra Boss Locations guide might help with that!

Rune Slayer Rune Key

The Rune Key is one of the most sought-after items right now due to its ability to grant you access to the Tundra location.

How to Get the Rune Key

The obtainment method of the Rune Key is quite long-winded, but it all ultimately results in your unlocking the crafting recipe for the item.

Pick Up the Required Quest

The first thing you need to do is unlock the required quest. You can find the NPC providing this quest by heading directly from the beach area and going straight forward from the wooden docks.

Once the island comes into view, you can hop off your mount, walk ahead, and jump up twice before making your way to the right along the ledge. There should be a tree here, which is where the Soren NPC stands!

By interacting with him, he starts to talk about a mysterious whale, thus unlocking the quest.

Runic Whale Location

The Runic Whale spawns in the ocean area directly in front of the Soren NPC, whom you spoke to when unlocking the quest. If you’re struggling to find the boss, it often appears close to the Tundra Gate.

Obtaining the Runic Fragment

After revisiting Soren, once you defeat the Rune Whale, he then asks you to collect a variety of items. You need to obtain:

  • 1 Mutated Head
  • 3 Lobster Claws
  • 3 Lobster Shells
  • 3 Squid Tentacles
  • 3 Squid Mantles
  • 3 Shark Fins
  • 3 Shark Tooth
  • 3 Hammerhead Scales
  • 3 Whale Tails
  • 3 Whale Scales

After collecting these items and handing them in to Soren, you obtain the Runic Fragment.

Fragments of Power Quest

The final quest is Fragments of Power. This requires you to defeat multiple bosses across the map so that you can ‘collect’ their souls. The bosses you need to beat are:

  • Slime King
  • Dire Bear
  • Elder Treant
  • Mother Spider
  • Licht King
  • Goblin King

Crafting the Rune Key

Once you defeat all the bosses listed above, you can head back to Soren. In return, he gives you the Rune Key Crafting Recipe. Go into your inventory and select the Rune Key Crafting Recipe item to unlock the ability to use the recipe at a crafting bench. Luckily, you only need 1 Runic Fragment, which you already have.
