Quick Guide
  • Undealt forge guide: The forge turns idle loot into real power via upgrades, rerolls, and crafted gear.
  • Materials first: Salvage white/green gear into Scrap Metal — never sell it for gold.
  • Weapon priority: Forge weapons for your two damage dealers before armor or support gear.
  • Reroll discipline: Only spend Cursed Essence on rare+ items with a good base.
  • Market check: Check Steam Market prices before salvaging tradeable endgame drops.

How the Undealt Forge Works

The forge is where Undealt's loot loop comes together. While your four heroes battle automatically in the corner of your screen, the forge is where you convert drops into progression: upgrading gear levels, rerolling secondary affixes, and spending materials earned from salvaging the constant stream of idle loot.

Three core activities define the system:

Gear Upgrading

  • Combine duplicate gear pieces plus Scrap Metal
  • Raises item level and base stats
  • Best for weapons you will keep long-term

Affix Rerolling

  • Spend Cursed Essence to reroll secondary affixes
  • Only worth it on rare or higher items
  • Shapes gear toward your build

Salvaging

  • Converts unwanted drops into forge materials
  • White/green gear should nearly always be salvaged
  • Feeds every other forge activity
Common Mistake

Do not invest enhancement materials into common or low-rarity items. Early loot is temporary — save your materials for gear you will keep across multiple stages.

Forge Materials & Where to Farm Them

Every forge recipe draws from a small set of materials, each with a distinct source. Knowing where each material comes from prevents wasted farming time and keeps your idle loop efficient.

MaterialSourceUsagePriority
Scrap MetalIdle stage drops, salvaged white/green gearNearly every early forge recipeNever sell — always keep
Cursed EssenceElite enemies, boss killsHigh-tier crafts and affix rerollsReserve for rare+ items
Duplicate GearStage drops of same itemGear upgrading inputBank for weapons first
Tradeable DropsEndgame boss killsSteam Market sales or forge inputCheck market price first

Elite enemies and bosses are your best targets when you specifically need Cursed Essence. Regular idle stages produce a steady trickle of Scrap Metal and duplicates, which is exactly what early upgrading consumes.

Farming Tip

Park your party on the highest stage they can clear reliably rather than a stage where they die repeatedly. Reliable clears maximize material throughput per hour, both online and for offline idle rewards.

Step-by-Step: Forging Your First Gear Set

Follow this sequence in your first few hours to get the biggest power spike from limited materials.

1

Salvage the Flood

White and green drops come faster than you can equip them. Salvage everything your heroes are not wearing into Scrap Metal — selling yields almost nothing by comparison.

2

Forge Weapons for Damage Dealers

Upgrade weapons for your two damage-dealing heroes first. Clearing stages faster increases every income stream: gold, materials, and offline progress.

3

Armor the Frontline

Once damage stalls, forge armor for your frontline tank so the party survives harder stages. Frontline durability becomes essential as enemies hit harder.

4

Fill Support Gear

Equip and upgrade support gear last, then spread forges evenly once every hero has a solid baseline set.

5

Reroll Only Good Bases

Once you own rare+ items with the correct main stat for your build, start spending Cursed Essence on rerolls. Never reroll blue or lower items.

Why Weapons First

Flat weapon damage boosts every build archetype and shortens every battle. Faster clears compound into more loot per hour, which compounds into more forge materials — the single best early investment.

Loot Handling: Keep, Salvage, or Sell

The forge only works well if you feed it the right items. Use this decision table every time your mailbox fills up with drops.

Before You Salvage

Always check the item tooltip for the tradeable icon before salvaging endgame boss drops. Regular leveling loot is account-bound, but certain rare endgame equipment and materials can be listed on the Steam Community Market for actual value — salvaging those can be a costly mistake.

Forge Priority by Game Phase

Forging priorities shift as your party progresses. What wins stages early is not what sustains late-game scaling.

PhaseForge FocusRationale
Early GameDPS weaponsRaw damage pushes stages fastest; support feels weak here
Mid GameFrontline armorEnemies hit harder; tank durability becomes the bottleneck
Late GameSupport gear + rerollsSupport buffs multiply whole-party power; refine affixes for builds

Idle Pushing Setup

  • Prioritize stage-clear speed over boss burst
  • Farm the highest reliable clear stage
  • Stack economy cards like Loot Whisperer while idling

Endgame Setup

  • Reroll affixes toward your build's core stats
  • Reserve Cursed Essence for elite gear
  • Bank tradeable drops for market spikes
Card Synergy

Forging and the card system reinforce each other. A Loot Whisperer card in your farming deck increases gold and material drops, which directly accelerates your forge output during long idle sessions.

Forge Mastery Checklist:

  • Salvage all white/green gear instead of selling
  • Forge weapons for both damage dealers first
  • Complete frontline armor baseline set
  • Reserve Cursed Essence for rare+ rerolls
  • Check Steam Market before salvaging tradeable drops

FAQ

Q: Should I sell or salvage low-rarity gear in Undealt?

Salvage it. White and green gear sells for almost no gold, but salvaging yields Scrap Metal used in nearly every early forge recipe — far more valuable over time.

Q: What should I forge first as a new player?

Forge weapons for your two damage dealers first, then armor for your frontline tank, then support gear. Faster stage clears increase all income, making weapons the highest-return early investment.

Q: When is affix rerolling worth it?

Only spend Cursed Essence to reroll secondary affixes on rare or higher items that already have a good base and the correct main stat for your build. Never reroll blue or lower gear.

Q: How does the Steam Market affect forge decisions?

Certain endgame boss drops are tradeable on the real Steam Community Market. Always check current market prices before salvaging them — some items are worth more sold than forged.
