Sulfur Game Quests: How to Complete Vendor Tasks

Quests in Sulfur are fetch tasks offered by wandering and church vendors that reward you with stamps. You redeem these stamps at Arthur in the church hub to unlock facilities, expanded storage, and essential camp utilities.

What Are Quests in Sulfur?

Quests are delivery errands assigned by thirteen individual merchants across dungeons and the sanctuary hub. When you speak to a trader in the field or back at The Original Sin church, they present orders for everyday consumables, monster drops, or weapons. Delivering the requested item count immediately pays out stamps, the central progression currency for town infrastructure.

Developer Perfect Random introduced a digital quest tracker in the 1.0 update on the Steam store page, replacing the older need to memorize requests or record them manually. The official website highlights this loop of venturing out for salvage and returning to expand the parish. Turning in tasks requires specific items, but merchants do not reset their active requests on their own.

How Do You Complete Vendor Quests?

Completing vendor tasks requires collecting specific loot during a dungeon dive and delivering the exact stack count to the corresponding merchant.

1. Interact with a merchant in town or during an expedition through the levels to inspect their dialogue and open orders.
2. Scavenge the demanded quantity of trade goods, raw ingredients, or cooked meals from breakable containers and enemy drops.
3. Bring the items back to the requesting vendor either on foot or by returning to the church hub.
4. Hand over the items through their interaction window to collect your reward stamps.
5. Deposit your surplus quest items in the shared church stash or an unlocked toilet before heading back into danger.

Vendors have distinct item pools, making targeted runs effective once you recognize their preferences.

How Should You Spend Stamps at Arthur?

Arthur is the church contractor who trades facility renovations for your quest stamps. The upgrades he sells expand your capabilities between expeditions and safeguard high-value loadouts against sudden death. Because stamps require deliberate scavenging, prioritize town unlocks that directly boost your farming efficiency and item safety.

If you need a quick restock of specific vendor stocks, the delivery demon can refresh shop selections for one stamp, which also helps cycle characters appearing at the Holo Reality Projector.

Which Items Should You Stash for Quests?

Hoarding the correct crafting materials and drops ensures you can instantly clear requests the moment a vendor appears. Certain items drop constantly in early areas like the Caves, while others require specific crafting preparations at a cooking pot.

• Sticks: The most versatile quest item in the game; combine two sticks to form sawdust, or use them for skewers, stick grenades, and cotton candy.
• Cheese: The exclusive trading commodity for Scrip, yielding high stamp payouts when converted into meals using food recipes.
• Dog Eyes: Aim directly at the head when eliminating hounds to sever eyes for Grossberg and the Hawklin Salesman's discount card.
• Wet Wipes: Crucial maintenance consumables required by Ralphie; these are rare drops best scavenged through the Sewers.
• Rocks and Earthworms: Abundant items that satisfy Bill and Grave Digger without taking up valuable premium weapon lockers.
• Cooked Dishes: Stockpile hard shell tacos, burgers, and stews in your shared containers so you can turn them in without hunting for wild cauldrons.

Taking advantage of these requests speeds up your compound unlocks, letting you store spare gear before experimenting with high-tier gun builds in dangerous biomes.
