The Blacksmith's Shop sits within the city district, typically nestled among other craft buildings like the Carpenter and Baker. Players should approach from the main city entrance, moving past the chapel area and pushing deeper into the urban zone. The shop is identifiable by its heavy reinforced door, which requires the Blacksmith Key to open.
The city area is densely populated with enemies, including Screamers, Leapers, and Fleshkin. Always clear the surrounding buildings before attempting to unlock the Blacksmith's door. Leaving spawn points unblocked can result in being swarmed while looting.

Crafting Material Values
| Material | Rarity | Primary Use | Approx. Value |
|---|---|---|---|

| Heat-Treated Iron | Rare | High-tier weapons | High |
| Silver Ore | Uncommon | Special upgrades | High |

Step-by-Step Blacksmith Key Run
Executing a successful Blacksmith run requires careful planning, proper loadout, and awareness of enemy spawns. Follow these steps to maximize your loot while minimizing risk.
Prepare Your Loadout
Bring a weapon with high projectile or melee damage, bandages, health potions, and most importantly, an empty or near-empty backpack. The crafting materials inside the Blacksmith's Shop are heavy, and you will need every slot available.
Enter the City District
Start your raid and beeline toward the city area. Avoid unnecessary detours through the catacombs or caves unless you need to gather additional supplies. Move as a group if playing co-op.
Clear Surrounding Enemies
Before approaching the Blacksmith's door, eliminate all Screamers, Leapers, and Fleshkin in the vicinity. Block nearby spawn points by closing doors and positioning teammates at chokepoints.
Unlock and Loot Systematically
Use the Blacksmith Key on the reinforced door. Start with the ground floor, grabbing the anvil and ingots. Then move upstairs for schematics and heat-treated components. Watch out for the exit trapdoor near the stairs.
Extract Safely
After looting, head toward the chapel extraction point or the abandoned siege tunnel. Be prepared for enemy waves on the way out, especially near the city outskirts.
In co-op runs, designate one player as the key holder and looter while others provide overwatch. The looter should focus entirely on grabbing items while teammates block doorways and eliminate any enemies that spawn. Share duplicate crafting materials like crucible tongs and handsaws on the ground for easy pickup.
City Key Comparison
The city district in Expedition Into Darkness contains multiple locked buildings, each requiring a specific key. Understanding the differences helps you prioritize which keys to carry and which buildings to target during a run.
| Key Type | Building | Primary Loot | Priority |
|---|---|---|---|
| Blacksmith Key | Blacksmith's Shop | Anvils, ingots, schematics | High |
| Mason Key | Mason's Workshop | Ore, limestone, silver | Medium |
| Carpenter Key | Carpenter's Shop | Wood, shafts, grips | Medium |
| Baker Key | Bakery | Consumables, food | Low |
| Alchemist Key | Alchemist's Lab | Potions, reagents | High |
| Fletcher Key | Fletcher's Shop | Arrows, fletchings | Low-Medium |
You can carry multiple keys simultaneously. Prioritize the Blacksmith Key and Alchemist Key for maximum value per run. The Mason Key is a solid secondary choice if your backpack still has room after the Blacksmith's Shop.
Enemy Threats in the City
| Enemy Type | Threat Level | Behavior | Counter Strategy |
|---|---|---|---|
| Screamer | Medium | Alerts other enemies | Kill before it screams |
| Leaper | High | Jumps at players | Watch vertical angles |
| Fleshkin | Medium | Group spawns | Area damage weapons |
| Bog Matriarch | High | Drops oil and ink | Focus fire, keep distance |
| Bladder (Explosive) | Medium-High | Explodes on death | Bait explosion, then retreat |
| Rasper | Medium | Cave ambushes | Block narrow passages |
| Elite Enemies | Very High | Heavy damage | Team focus, use potions |
Crafting Strategies with Blacksmith Loot
The materials obtained from the Blacksmith's Shop directly feed into some of the most powerful weapon upgrades in the game. Understanding how to use these materials efficiently can give you a significant edge in subsequent raids.
Weapon Upgrades
- Heat-treated iron enables rare one-handed axes
- Falcon blades create fast, high-damage swords
- Great wood grips improve sword handling
- Bastard sword blades for versatile two-handers
- Crossbow cranks for heavy draw weights
Camp & Bench Upgrades
- Handsaws required for bench upgrades
- Nails and rivets for structural projects
- Anvils unlock advanced smithing
- Complex schematics unlock new recipes
- Short supports for camper upgrades
Do not waste heat-treated iron on common weapons. Save it for one-handed axes or bastard swords, as the damage scaling on these weapon types benefits most from rare materials. If you find a falcon blade with a notable bronze tier or higher, prioritize crafting a sword around it rather than using a standard blade.
Weapon Crafting Priority
| Weapon Type | Material Cost | Damage Output | Recommended For |
|---|---|---|---|
| One-Handed Axe | Heat-treated iron, shaft | High | Close-quarters combat |
| Bastard Sword | Uncommon blade, grip | Very High | Versatile engagements |
| Falcon Blade Sword | Falcon blade, wood grip | Medium-High | Fast attack speed |
| Crossbow (Upgraded) | Crank, fletchings | High (ranged) | Enemy crowd control |
| Kettle Hat | Iron, nails | Defense | Head protection |
Extraction Routes After Looting
Once you have cleared the Blacksmith's Shop, choosing the right extraction route is critical. Carrying heavy loot slows you down, making you vulnerable to enemy waves that spawn as the raid timer progresses.
Pre-Extraction Checklist:
- Anvil secured in backpack
- All ingots and heat-treated components collected
- Complex schematics picked up from upstairs
- Health potions and bandages ready for extraction fight
- Team regrouped at agreed rally point
- Spawn points blocked with doors or barrels
The chapel extraction is reliable but well-known to enemies. The abandoned siege tunnel offers an alternative route but contains its own threats, including Raspers and corpse-type enemies. Always check your surroundings before committing to an extraction point.
Extraction Point Comparison
| Extraction Point | Distance from Shop | Safety Level | Enemy Density |
|---|---|---|---|
| Chapel | Medium | Medium | High |
| Abandoned Siege Tunnel | Short | Low-Medium | Medium-High |
| City Wall Breach | Short | Low | Variable |
| Suburb Path | Long | Medium | Medium |
Frequently Asked Questions
Q: Can I find the Blacksmith Key in every raid?
The Blacksmith Key does not appear in every raid. It has a randomized spawn pattern and can be found as enemy drops, in loot chests, or obtained through co-op sharing. If you cannot find it during a run, focus on other objectives and try again in the next raid.
Q: What is the most valuable item in the Blacksmith's Shop?
The anvil is typically the highest-value single item, followed closely by complex schematics and heat-treated iron components. The anvil is essential for workshop upgrades, while schematics unlock new crafting recipes that persist beyond the current raid.
Q: Can I share the Blacksmith Key with teammates?
Yes, keys can be shared in co-op mode. One player can carry the key and unlock the door for the entire team. Coordinate beforehand so that the player with the most inventory space handles the looting while others provide security.
Q: Is the Blacksmith Key better than the Mason Key?
The Blacksmith Key generally provides higher-value loot focused on weapon crafting materials and schematics. The Mason Key offers ore and limestone, which are useful but less versatile. If you can only carry one, prioritize the Blacksmith Key unless you specifically need masonry materials.
Q: What should I do if the complex schematic is bugged?
There have been reports of the complex schematic being unable to be picked up due to inventory detection issues. Try dropping items to free space, checking your belt slots, or having a teammate attempt pickup. If the bug persists, the schematic may require a game update to fix.
