The Skull Key in Dark and Darker grants you access to a secret area in your dungeon, where you can earn high-value loot.
Dark and Darker: How to Get the Skull Key and Unlock the Skull Door – Legendary Loot Guide
While earning Legendary Status by using Redstone Shards is the best way to enter high-roller dungeons and earn high-value loot, you can also look for specific drops like the Skull Key, which bosses sometimes drop on the map. Here's everything you need to know about the Skull Key in Dark and Darker.
To get a Skull Key in Dark and Darker, you’ll need to defeat bosses like Ghost King, Skeleton Warlord, and Lich. The item’s spawn isn’t guaranteed though, as the item’s drop rate is two percent for killing Ghost King and half a percent for the other two bosses. Getting the elite version of the bosses, which are incredibly tougher than their regular versions, bumps the drop rate to five percent, but their spawn is dependent on your luck. So don’t shy away from a good fight to stand a chance at quality loot.
Your best chance of finding the Skull Key is to defeat the Ghost King, who spawns in the center of the map on the Inferno map, as indicated by the Dot Marker. The Ghost King is a dangerous boss that often teleports to the player and gives them a debuff that deals damage efficiently. He also spawns three flying Death Skulls, which are easy to take down but can also act as a distraction and leave you open to damage. So keep your eyes on the target.
