Dome Keeper Guild Quests Guide: Strategies for Every Assignment

To clear Guild Quests in Dome Keeper, adjust your initial build order to counter the primary handicap of each assignment before expanding your mine. Unlike standard runs, Guild Quests impose strict operational rules, resource quotas, or combat penalties. Surviving requires prioritizing defense stability, tightening your return trips, and budgeting iron around the active contract objective.

Core Assignment Modifiers

Each Guild Quest alters base gameplay conditions, shifting priority away from greed-driven mining toward specific defensive requirements.

Assignment	Primary Challenge	Priority Investment	Main Risk
Showdown	Fast wave escalation	Weapon tracking and base damage	Falling behind on wave kill speed
Iron Donation	Guild quota tax	Digging speed and carry capacity	Starving weapon upgrades
Broken Weapon	Sluggish, impaired main weapon	Defensive gadgets, stuns, and repairs	Long fights causing excessive dome damage
Heavy Hitter	High-damage brute enemies	Concentrated burst damage and overcharge	Getting one-shot by heavy melee hits

Showdown: Handling Compressed Wave Timers

The Showdown contract accelerates combat pressure, featuring faster enemy escalation and intense engagements that leave minimal time for subterranean exploration.

Upgrade base weaponry first: Spend your earliest iron on weapon tracking speed, damage, or projectile velocity. Do not purchase utility gadgets until you can reliably defeat early flyers and ranged spitters before they stack incoming damage.
Keep a compact dig pattern: Dig narrow, vertical shafts directly beneath the dome. Limit travel time so return trips stay under ten seconds.
Reserve iron for repairs: Keep two to three iron unspent in reserve to handle emergency hull repairs between cycles.
Ascend early: Begin returning to the surface when the threat meter passes the halfway mark to ensure you are seated at the console before monsters spawn.

Iron Donation: Managing the Resource Tax

The Iron Donation quest requires submitting a mandatory iron quota to the guild, restricting the amount of metal available for tech progression.

Splitting Your Iron Income

Do not deposit all your iron at once, as doing so leaves your dome defenseless against scaling threats. Split your income across distinct phases:

Phase 1 (Survival baseline): Invest the iron from your first two mineral veins entirely into core upgrades: Tier 1 drill strength, initial carry capacity, and base weapon tracking.
Phase 2 (The 50/50 split): Once your drill can cut through secondary rock layers, deposit half of every haul into the guild repository while reinvesting the other half into weapon damage.
Phase 3 (Final delivery): Only deliver the final quota surplus once your dome has sufficient combat power to survive the current wave tier.

Skip luxury utility gadgets in this assignment to avoid delaying your donation quota.

Broken Weapon: Layering Defensive Gadgets

The Broken Weapon assignment hampers your offensive reliability through delayed weapon response, intermittent failures, or reduced damage output. Because primary weapons cannot clear waves quickly, defense must absorb extended combat encounters.

Rely on the Shield or Repellent: Use these primary defensive gadgets to absorb initial impacts or delay wave advances during weapon downtime.
Focus high-threat targets: Eliminate dive-bombing flyers and explosive burrowers first, letting slower melee ground units hit shields while waiting on weapon recovery.
Upgrade repair efficiency: Enhanced repair output ensures each spent piece of iron restores maximum hit points during drawn-out attacks.
Use crowd control: Secondary attachments with stun charges or shockwaves keep enemy clusters immobilized during weapon malfunctions.
Dig straight transit paths: Keep mining corridors straight and clear of debris to ensure fast return trips during shortened recovery windows.

Heavy Hitter: Countering High-Impact Enemies

The Heavy Hitter assignment features brute variants capable of breaking shields and wrecking hull glass in a few strikes. Standard attrition builds fail against these targets; you must prevent heavy melee units from ever making contact with the dome.

Prioritize burst damage: Upgrade your weapon for concentrated single-target bursts—such as heavy laser focus or weighted sword strikes—to eliminate brute targets at long range.
Mine for cobalt and water: Prioritize high-density rock layers to locate cobalt for structural reinforcement and water to power combat overcharge abilities.
Trigger defensive overcharge immediately: If an armored heavy unit closes the distance to the dome wall, activate your gadget overcharge right away rather than trying to trade melee blows.
