The Forge Fungi Shop explained: Item pool, daily rotation, and maze location

The Fungi merchant in The Forge is one of the most important NPCs added with the Hidden Maze update. He sits behind a small shop deep inside Iceberg Island’s maze and sells a compact set of items that directly affect mining efficiency and late-game weapon progression. The catch: you pay Coinite to enter the island, the maze layout can shift, and the merchant’s exact room changes day to day.

Fungi Shop basics: what the merchant actually does

The Fungi Shop is a special vendor found inside the Hidden Maze on Iceberg Island. It is run by a mushroom-like NPC simply called Fungi or the Fungi Merchant. Unlike general-purpose vendors, this shop focuses on a very small pool of high-value items:

• One consumable, Fungi’s Potion, that buffs mining speed, damage, and luck for a limited time.
• Eight weapon blueprints that permanently unlock new forging recipes for late-game weapons.

Only five items are on display on any given day. Fungi’s Potion is always present, and the remaining four slots are filled by random weapon blueprints from the pool. The shop’s stock refreshes once per day and the potion quantity resets, which makes the merchant a recurring stop rather than a one-time visit.

All Fungi Shop items and prices

The merchant draws from a fixed pool of nine items. The table below lists every item, its cost, and what it unlocks.

Each blueprint purchase permanently adds the corresponding weapon recipe to your forge menu. After that, you can craft that weapon as many times as you like, provided you have the right ores and money.

How Fungi’s Potion works

Fungi’s Potion is the only consumable in the shop and the easiest purchase to justify early on. When you drink it, you gain:

• 20 percent faster mining speed
• 15 percent extra mining damage
• 15 percent extra luck
• A duration of 600 seconds (10 minutes)

Because the potion boosts both throughput and luck, it pays off fastest when you use it on dense ore routes or inside higher-value areas like Raven Cave or deeper sections of the maze. The merchant usually offers several copies per day, and that stock refills on the next refresh, so you can safely treat it as a repeatable part of your mining routine instead of something to hoard forever.

How the Fungi Shop rotation and restock behave

The merchant follows a predictable structure, even if the item mix looks random at first glance.

• The total pool is fixed at nine items: one potion and eight blueprints.
• Each day, the shop displays five items: Fungi’s Potion and four randomly selected blueprints.
• Fungi’s Potion appears with multiple charges you can buy in one day.
• Each blueprint in that day’s rotation has a single stock; once purchased, it disappears until a future day.
• The entire inventory, including potion charges, resets with the daily refresh.

There is no way to force a specific blueprint to appear. If the weapon you want is not in the current rotation, the only reliable path is to re-run the maze after the next daily reset and check again.

How to reach Iceberg Island and the Hidden Maze

Access to the Fungi Shop is gated behind Iceberg Island’s Hidden Maze. The game expects that you already have basic progression into Frostspire Expanse, Coinite income, and enough combat power to handle tougher enemies.

Step 1: Travel to Frostspire Expanse using the usual world travel methods or your Portal Tool if you have it unlocked. Head toward the docks area where the ferry operator stands.

Step 2: Farm at least one Coinite by mining red crystals in areas like Raven Cave or the Heart of the Islands. Medium and large red crystal nodes are the most efficient targets.

Step 3: Talk to the ferry captain at the Frostspire dock and pay 1 Coinite to board the boat. The ferry moves you to Iceberg Island after a short countdown. Swimming across is blocked by a kill barrier, so the boat is mandatory.

Step 4: Once you land on Iceberg Island, move inland until you find the large hole leading down to the Hidden Maze entrance. Jump in to load into the maze itself.

Each ferry ride costs another Coinite, so bringing a small buffer of ore is useful if you expect to leave and re-enter the maze several times in one session.

Finding Fungi inside the Hidden Maze

The maze on Iceberg Island is designed to waste your time if you rush it. The layout can reset, pirate enemies hit harder than regular mobs, and the Fungi Shop room is not anchored to a single coordinate. Still, the early turn pattern that leads toward the merchant has been consistent across runs.

Step 1: From the maze entrance, move forward until you reach the first junction, then take a left turn.

Step 2: At the second junction you encounter, turn left again.

Step 3: At the third junction, repeat the pattern and turn left one more time.

Step 4: The fourth junction breaks the streak: turn right here.

Step 5: At the fifth junction, turn right again.

Step 6: Continue until you reach a crossroads; going straight ahead from this point leads into the Fungi Shop room.

After interacting with the shop, some paths to the right of that room continue deeper into the maze and toward other content, including the angelic questline and Heavenly Pickaxe route. Expect minor variation between days, but treating the maze like a grid and clearing methodically keeps backtracking under control.

Enemies you face on the way to the Fungi Shop

The Hidden Maze is a combat zone, not a safe corridor. Pirate-themed enemies there have noticeably more health and damage than surface mobs, and some variants function as mini-bosses with larger health pools.

Before committing to a maze run, it helps to:

• Equip armor recipes that focus on survivability, not just damage.
• Bring weapons you are already comfortable with rather than untested crafts.
• Consider using potions outside Fungi’s inventory if you struggle to survive multiple pulls.

Dying halfway through the layout wastes your Coinite ferry cost and your time, so it is entirely reasonable to overgear these runs rather than treating them like casual mining trips.

How Fungi blueprints plug into the broader blueprint system

Fungi’s weapon blueprints are part of the wider blueprint system introduced with the Winter Expansion. Blueprints effectively act as permanent recipes. Once you buy a blueprint from the Fungi Shop, it appears alongside your existing forge options and can be crafted again whenever you have the materials and cash.

Outside the seasonal Hell Slayer and Candy Cane weapons that are no longer active, the key blueprints currently tied to Fungi are:

• Crystalized Broadsword at $290,000
• Anchored Straight Blade at $260,000
• Shark’s Fangs at $80,000
• Executioner’s Great Axe at $380,000

These blueprints sit in the same system as other late-game recipes and are meant to drive long-term builds rather than serve as short-lived upgrades. Once acquired, they are particularly useful when combined with high-tier ores and trait-focused forges.

What to buy first from the Fungi Shop

Gold in The Forge is finite on any given day, and the merchant’s prices reflect that. Treating Fungi’s inventory like a checklist you must complete immediately is a good way to stall your progression elsewhere.

For most players, a simple priority order works well:

• First purchase: Fungi’s Potion. Even one or two potions dramatically increase income during organized mining runs. That, in turn, makes future blueprint purchases less painful.
• Second: a blueprint that matches your playstyle. Heavy builds should look at Executioner’s Greataxe, Anchored Greatsword, Colossal Gemblade, or Colossal Terrorblade. Faster or more agile builds gain more value from Shark’s Fangs, Crystalized Broadsword, or Anchored Straight Blade. Spear fans have Knight Spear as a natural target.
• Later: fill in off-build options. Once your main weapon lane is covered and your income is stable, picking up “sidegrade” blueprints gives you flexibility to experiment without re-running the maze only for variety’s sake.

Buying a blueprint for a weapon type you never intend to use is simply a sunk cost; the shop’s rotation model makes patience more valuable than fear of missing out.

Money and Coinite planning around daily visits

Because Fungi’s inventory and the maze layout refresh daily, the shop rewards players who treat it like a recurring errand instead of a one-off sprint. That has two practical implications: you need repeatable Coinite income to fund ferry trips, and you need steady cash to exploit the blueprint rotation when a desired item finally appears.

In practice, that means:

• Running Coinite routes in Raven Cave or Heart of the Islands regularly, focusing on medium and large red crystals.
• Using Fungi’s Potion only during your highest-yield mining windows so its 600-second timer translates directly into more gold or rarer ores.
• Keeping a reserve of money for blueprints so you can buy on sight instead of waiting another full cycle.

Veteran players tend to fold the maze and Fungi Shop into a wider daily loop that also covers AFK farm spots, high-value ore areas, and any open quests on Frostspire Expanse or nearby islands.

The Fungi Shop sits at the intersection of exploration, resource planning, and buildcraft in The Forge. Once you know how the daily rotation works and how to reach the merchant reliably, it turns from a frustrating scavenger hunt into a predictable part of your progression routine: buy the potion, grab the right blueprint when it appears, and let the maze runs pay for themselves.
