Stardew Valley Skull Cavern Guide - Location, Strategies, Treasure, & More

Posted on by justin
Don’t mistake Stardew Valley for not offering anything more than a lifestyle farming simulator. ConcernedApe’s hit title also has various dangers in it. However, brave these hazards and you can be graciously rewarded. One of the most dangerous locations you can face in Stardew Valley is Skull Cavern, and we’re here to guide you through this perilous space.

Stardew Valley Skull Cavern: An Overview

Stardew Valley Skull Cavern Guide Similar to the Mines, Stardew Valley players must go through numerous subterranean floors that increase in difficulty. But unlike the Mines, the Skull Cavern in Stardew Valley has no elevator. That means you can’t skip floors and would always start from Floor 1 for each run. However, a ladder exists on every floor that’ll lead you back up to the surface if you want to quit the run. As for going down, you must search for holes that’ll drop you 3 to 15 floors at a time, depending on RNG. Note: Jumping down more than three floors will cause damage. Moving forward, the Skull Cavern is a great place to farm Iridium Ore. The chances of finding this valuable mineral increase as you go further down the dungeon. You may also increase the opportunities of Iridium Ore dropping from mineral deposits if exploring the dungeon during a lucky day, as dictated by the Fortune Teller on your farm’s Television. But be wary because Prehistoric Floors may randomly appear in Skull Cavern. You’ll know if you’re in one when Pepper Rexes (added in version 1.4) mostly appear on that floor. You must defeat all these enemies before you can proceed to the next floor. Also, dying while in Skull Cavern will respawn you in Harvey’s Clinic. But the town’s doctor will charge you 1,000 gold pieces for his services. Persevere and survive, you can reach the 100th floor, which is a guaranteed treasure room. But if you read Secret Note #10, this floor transforms into Mr. Qi’s hideout, where you can now trade items and take on additional side quests.

Location and Entry Requirements

Travel to the northwest area of the Desert to find the entrance to the Skull Cavern. The closed entrance prevents you from progressing without the Skull Key. So, venture into the 120th floor of the Mines to receive this item so you can enter the Skull Cavern. Note: You can also use the Skull Key to unlock the Junimo Kart arcade game in Gus’ Saloon.

Like taking on the Mines, trying to reach Floor 100 of Skull Cavern in Stardew Valley doesn’t require specific steps. Use different strategies and tactics to your liking to complete this in-game dungeon. Some of the ideas you may take advantage of are the following:
Use Explosives
Trying to find the hole in Skull Cavern to lead you to the lower levels can be tedious. Instead of cracking open each stone or mineral deposit on each floor, use explosives to search a wider area than the pickaxe.
Place Staircases
If you don’t mind going through the levels one by one instead of jumping down holes, bring Staircases with you to Skull Cavern. With this item, you don’t have to use your pickaxe or explosives to search for holes. However, crafting one Staircase requires 99x Stone. You can buy Stones from Robin’s Carpenter Shop for 20 to 100 gold pieces each. But buying one would cost 1,980 to 9,900 gold pieces, which can be fairly expensive for some new and veteran Stardew Valley players.
Bring Food
Often, you’d jump several floors to reach Floor 100 in Skull Cavern. But that also means damaging your health. Avoid dying before reaching the final floor by bringing food items. Some excellent examples include Maple Bar, Pumpkin Soup, and Crab Cakes since these options regenerate 200 health or more for each use.
