Mining and Combat

Tactical Quick Answer

The Mines run 120 floors with an elevator checkpoint every 5 floors, and each section yields a different ore: Copper from floor 2, Iron from 41, and Gold from 81. Always bring a large stack of food, because reaching zero health makes you pass out and drop gold and random items, though Marlon at the Adventurer's Guild will sell one lost item back to you. The Skull Cavern needs both the Skull Key from floor 120 and a repaired bus, and it has no elevator at all.

Mining provides the raw materials necessary to upgrade your tools, craft sprinklers, and process Artisan Goods. The deeper you go, the better the loot, but the monsters become significantly more dangerous.

The Mines​

The Mines, located in the mountains north of Pelican Town, consist of 120 floors. You progress by breaking rocks to find the ladder leading to the next floor.

An elevator saves your progress every 5 floors (5, 10, 15, etc.). Always aim to reach the next elevator checkpoint before leaving the Mines for the day.

Resource Nodes​

The Mines are divided into three distinct sections, each offering different primary ores:

  • Floors 2-39: Copper Nodes. The monster roster splits in two here. Floors 2 to 29 give you Green Slimes, Duggies, Bugs, Rock Crabs, and from floor 11 Grubs and Cave Flies. Floors 31 to 39 drop the slimes entirely and hand you Bats and Stone Golems instead.
  • Floors 41-79: Iron Nodes, in a frozen environment. Frost Jellies, Frost Bats, and Dust Sprites, adding Ghosts from 51 and Skeletons from 71.
  • Floors 81-119: Gold Nodes, in a volcanic environment. Red Sludges, Lava Bats, Lava Crabs, Shadow Brutes, Shadow Shamans, and Metal Heads, adding Squid Kids from 91.

Floors 40 and 80 are reward floors with a chest and no ore, so the ore bands start on 41 and 81.

Floor 120 holds the Skull Key, not a ladder. Taking it opens the Skull Cavern door in the Desert and the Junimo Kart machine in the Saloon, puts the Lava Katana in the Adventurer's Guild stock, and permanently strengthens most Mines monsters. There is also a Stardrop in a chest on floor 100 on the way down, which is a permanent max-energy increase and one of the seven you need for Perfection.

Mining Strategy​

  • Watch the TV: Check Welwick's Oracle before you commit. Good daily luck raises ladder drops from rocks, raises Gem Node and Mystic Stone spawns, improves Skull Cavern treasure room odds, and cuts what you lose if you pass out. Killing a monster is the stamina-free ladder route at a flat 15% per kill, against roughly 2% per rock.
  • Bring Food: Never enter the Mines without a large stack of food. If your health reaches zero you pass out, lose 5% to 25% of your gold up to 15,000g, and drop a random slice of your inventory.

That loss is not permanent, which is the single most useful thing to know after a bad run. Rings and most tools are never dropped, the Galaxy Sword can never be lost, and lost tools arrive in the mail the next morning. For everything else, Marlon at the Adventurer's Guild runs an Item Recovery Service and will sell one lost item or stack back to you for its base value, halved if you have read Mapping Cave Systems.

  • Use Bombs: Once you unlock the recipe, use Cherry Bombs and standard Bombs to clear massive clusters of rocks instantly. This saves immense amounts of energy and time.

Combat Mechanics​

Combat in Stardew Valley is simple but requires timing. You swing your weapon to deal damage and knock monsters backward.

Weapon Types​

  • Swords: The most balanced weapon type. They swing quickly in a wide arc. Right-click puts you in a blocking stance, and a successful block cancels the hit outright instead of shaving a percentage off it. It also reverses the attacker's momentum and deals about half the blocked damage back if the monster was charging you.
  • Clubs/Hammers: Slow but powerful. Their secondary attack is an area-of-effect slam with heavy knockback, which can never land a critical hit.
  • Daggers: Fast, stabbing weapons with a narrow hitbox. Their secondary attack is four rapid stabs that pin the target in place until the final one knocks it away.

No weapon or special move costs energy. The cooldowns are 1.5 seconds for the sword block, 3 for the dagger, and 6 for the club, all halved by Acrobat at Combat level 10 and halved again by the Artful enchantment.

Always prioritize Swords or Clubs over Daggers for general exploration.

The Skull Cavern​

Skull Cavern needs two separate unlocks, and reaching the bottom of the Mines is only half of it.

  1. Take the Skull Key from the chest on floor 120. Reaching the floor is not enough, you have to collect it.
  2. Open the Desert, which means finishing the Vault Bundles at the Community Center or paying Joja 40,000g for the bus repair.

Then use the key on the door inside the cave in the Desert's northwest corner.

The Skull Cavern has no elevator. You start at Floor 1 every time you enter. The monsters hit significantly harder, and the layout is larger. This is the primary source of Iridium Ore, which becomes more common the deeper you descend, climbing sharply between floor 10 and floor 100 and then flattening out. That plateau is why serious runs target floor 100 instead of simply going as deep as possible.

Surviving the Skull Cavern​

  • Chase Shafts, Not Ladders: This is the mechanic the whole run turns on. One in five ladders you knock out of a rock is a shaft instead. The drop is usually 3 to 8 floors, but one time in ten it doubles to 11, 13 or 15, so the real range is 3 to 9, 11, 13 or 15. It costs 3 health per floor skipped and can never take you below 1 health, so even a 15-floor drop is survivable at any health total. Depth comes from shafts, not from clearing floors.
  • Bring Staircases: Craft Staircases using 99 Stone, unlocked at Mining level 2. Use them to bypass infested floors or long, spiral layouts. Once you have Crystalariums running, the Desert Trader swaps one Jade for one Staircase on Sundays, which is far cheaper than mining the stone.
  • Stack Bombs: You cannot afford to mine rocks individually with a pickaxe here. Bring dozens of Mega Bombs, which unlock at Mining level 8 and take 4 Gold Ore, 1 Solar Essence, and 1 Void Essence.
  • Healing Items: Carry unbuffed healing food such as Cheese or Salad. They restore around 50 health each, which is mid-tier and not enormous, but the point is that they carry no buff, so eating one mid-run will not wipe the buff you came in with.
  • Buff Food: Eat Spicy Eel (speed and luck) or Crab Cakes (speed and defense) before entering. You can hold one food buff and one drink buff at the same time, and a new buff food replaces only the food slot. Drink Coffee or Triple Shot Espresso for speed, or Ginger Ale, whose +1 Luck stacks on top of a food luck buff.

Note that an in-game hour lasts 54 real seconds in the Skull Cavern instead of the usual 43, except in multiplayer and on prehistoric floors, so you get more real time per day down there but your buffs cover fewer game hours.

Frequently Asked Questions​

How many floors are in the Mines in Stardew Valley?

The Mines have 120 floors, with an elevator that saves your progress every 5 floors. Floor 120 contains a unique reward and not another ladder, so aim for the next elevator checkpoint before you leave for the day.

What ore is on each floor of the Mines?

Copper Nodes from floor 2, Iron Nodes from floor 41 in the frozen band, and Gold Nodes from floor 81 in the volcanic band. Floors 40 and 80 are reward floors holding a chest and no ore, so the bands start one floor later than you might expect.

What is the best weapon type in Stardew Valley?

Prioritize Swords or Clubs over Daggers for general exploration. A sword's block cancels an incoming hit outright instead of reducing it, and reflects about half the damage back at a charging monster. Clubs slam for area damage with heavy knockback but can never crit. No special move costs energy.

How do you unlock the Skull Cavern in Stardew Valley?

Two things, and reaching the bottom of the Mines is only half. Take the Skull Key from the chest on floor 120, then open the Desert by finishing the Vault Bundles or paying Joja 40,000g for the bus repair. Use the key on the door inside the cave in the Desert's northwest corner.

How do you survive the Skull Cavern in Stardew Valley?

Chase shafts and not ladders. One in five ladders you break out of a rock is a shaft. It usually drops you 3 to 8 floors, and one time in ten that doubles to as much as 15. It costs 3 health per floor and can never take you below 1 health, so the drop is always survivable, and that is where depth actually comes from. Bring Staircases and Mega Bombs, and carry unbuffed healing food like Cheese so eating does not wipe your buff.

Do food buffs stack in Stardew Valley?

You can hold one food buff and one drink buff at once. A new buff food replaces the old food buff and leaves the drink alone. Food with no buff at all, like Cheese or Salad, never clears anything. Ginger Ale is worth knowing because its +1 Luck stacks on top of a food luck buff.
