GRAIN ROT Murch Workshop & Outpost NPCs

Murch and Biggy are the two Outpost NPCs who guide GRAIN ROT’s surface tutorial. Biggy pushes expansion, cleaning, and morale. Murch runs the workshop where artifact coins become random loot, blueprints unlock, and your demolition mallet enters the build loop. Understanding both NPCs prevents wasting gold on cosmetics before functional upgrades land.

This guide covers Murch’s systems, Biggy’s maintenance quests, and how workshop tools connect to underground extraction. For spending priorities after you earn currency, read Room Upgrades and Artifacts & Blueprints.

Who is Murch?

Murch introduces himself at the workshop after the tutorial elevator tease. Dialogue positions him as the Outpost’s technical expert — “most of the complicated things around here.” In practice Murch gates:

• Artifact coins — currency for the ball machine gacha
• Demolition mallet — starter tool for breaking weak constructs
• Cleaning supply sales — tied to Biggy’s morale systems
• Future launch systems — Enchantment & Repair Machine teased for 1.0

Murch also gives bonus coins on repeat visits when rapport dialogue triggers — co-op groups should talk to him every return before descending again.

Who is Biggy?

Biggy frames himself as “boss” with comic bravado while Murch handles real systems. Biggy’s tutorial beats require:

• Cleaning dirty floors
• Patching broken walls
• Building a throne (meme-tier construct goal)
• Expanding “empire” room layouts

Skipping Biggy maintenance slows room upgrade efficiency in demo feedback. Treat cleaning as onboarding, not optional fluff.

Artifact coin → gacha → unlocker pipeline

Murch’s core progression loop:

1. Receive artifact coins from Murch or underground rewards
2. Deposit coins in the ball machine (gacha) near the workshop
3. Receive a random artifact item — useful or surprising
4. Place artifact in the unlocker / opener machine
5. Obtain a permanent construct blueprint drop

Never feed glowy underground orbs directly into the ball machine without understanding the difference — surface coins vs deep-layer artifacts overlap in naming but serve linked pipelines. Full detail: Artifacts & Blueprints.

Demolition mallet from Murch

The mallet Murch provides is a demolition tool, not a primary Corrupted weapon. Tutorial dialogue explicitly warns it underperforms against Corrupted compared to dedicated combat gear unlocked via inventory tiers.

Best uses at the Outpost:

• Break expendable constructs for scrap
• Practice build rotation before underground blocking
• Feed scrap into fresh construct recipes

Underground, the mallet breaks weak furniture for Grinder fodder — see Grinder & Loot Loop.

Workshop room layout tips

Players who decorate precisely suffer most when rot elevator bugs destroy rooms. Until launch patches confirm stability:

• Keep paths clear between workshop, ball machine, unlocker, and elevator
• Avoid blocking Murch interaction radius with large constructs
• Rebuild functional blockers before aesthetic symmetry

Constructs & Furniture covers tactical vs decor priorities.

Launch workshop expansions

Full release adds systems Murch’s workshop likely hosts or neighbors:

• Enchantment & Repair Machine — gear maintenance (Enchantment & Repair)
• Legendary Gachas — expanded artifact tier
• New Outpost NPCs — additional vendors or quest givers
• Second Outpost floor — vertical expansion per launch features

We update this page when launch patch notes confirm exact workshop UI changes.

Co-op workshop etiquette

Shared Outpost means shared gacha outcomes affect everyone:

• Announce before spending pooled artifact coins
• Agree on blueprint priority — storage vs blocking vs cosmetics
• One player talks to Murch while others repair rooms to save time

Arguments at the ball machine waste extract windows. Set policy in Co-op Tips pre-session.
