If you are pushing deep into the Mines, the Adventurer's Guild is where your weapons and monster goals live. This guide lists which Mines floor unlocks each shop item, its price, and the kill count and reward for every Monster Eradication goal, based on the Stardew Valley Wiki.
Shop unlock rule: Deepest Mines floor reached (floor 10 to the bottom)
Priciest weapon: Galaxy Hammer, 75,000g
Slayer goals: 12 (Slimes at 1,000 is the largest)
Smallest goal: 30 Duggies for the Hard Hat
Shop items unlock by Mines depth
The Guild shop does not sell everything at once; items appear as you reach deeper Mines floors. Per the wiki, Rusty Sword and Wooden Blade need no condition and cost 250g each, then Femur unlocks at floor 10, Iron Dirk at 15, Silver Saber, Elf Blade and Steel Smallsword at 20, and Pirate's Sword and Cutlass at 25.
The Galaxy Sword (50,000g) requires bringing a Prismatic Shard to the Three Pillars in the Desert. Only after you have it do the Galaxy Dagger (35,000g) and Galaxy Hammer (75,000g) appear. So everything up to the 25,000g Lava Katana is Mines progress only; anything above needs the Desert. Slingshots unlock at floor 40 (500g) and floor 70 (Master, 1,000g) and cannot be sold back. The Wall Sword (2,000g) and Decorative Sword (10,000g) are décor, not combat gear.
All 12 Monster Eradication goals
1,000 Slimes: Slime Charmer Ring (25,000g to buy). Big Slimes and slimes in your Slime Hutch do not count.
150 Void Spirits (including Shadow Shamans and Brutes): Savage Ring (25,000g)
200 Bats: Vampire Ring (15,000g)
50 Skeletons: Skeleton Mask (20,000g)
80 Cave Insects: Insect Head (10,000g)
30 Duggies: Hard Hat (20,000g)
500 Dust Sprites: Burglar's Ring (20,000g)
60 Rock Crabs: Crabshell Ring (15,000g)
100 Mummies: Arcane Hat (20,000g)
50 Pepper Rex: Knight's Helmet (20,000g)
250 Serpents: Napalm Ring (30,000g)
150 Magma Sprites: Marlon's Phone Number (not sold)
Which goals to chase first
The cheapest goals by kill count are 30 Duggies, 50 Skeletons, 50 Pepper Rex and 60 Rock Crabs. The 80 Cave Insects goal gives the Insect Head weapon (20-30 damage, 4% crit), a useful early-mid option. The 1,000 Slimes and 500 Dust Sprites goals take a long time, so work on them alongside other progress. The Magma Sprites goal overlaps with Volcano Dungeon runs. This guide did not verify what each reward item does, so check in-game or on the wiki page of the item you want.
Budgeting tips
Before floor 40, consider relying on dropped weapons instead of spending 750g early.
Plan Claymore (2,000g, floor 45) and a 9,000g weapon at floor 90 as your two main purchases.
After clearing the bottom of the Mines, save 25,000g for the Lava Katana.
Let kill goals build up naturally during Mines and Skull Cavern runs and finish only the rewards you want.
💡 Tip: The Slimes goal ignores Big Slimes and Slime Hutch slimes, so do not try to farm it in your hutch.
