- Undealt offline progress keeps earning rewards while the game is closed, based on your highest reachable stage.
- Farm a clearable stage: park your party where they win reliably, never where they die repeatedly.
- Claim from the mailbox: accumulated idle rewards wait for you when you return.
- Speed-clear builds outperform boss-burst builds for offline farming income.
- Cap awareness: rewards accumulate up to a capped duration, so claim regularly.
How Undealt Offline Progress Works
Undealt is a corner-screen idle RPG where four heroes battle automatically — and the loop continues even when the game is closed. Undealt offline progress is calculated from your highest reachable stage, not the stage you were last manually grinding. Rewards accumulate up to a capped duration, which means long absences eventually stop producing income until you return and claim.
The core mechanic is simple but often misunderstood: the game measures what your party can clear, then pays out accordingly. This is why setting up the right farming stage before you log off matters more than pushing one stage further before bed.
| Mechanic | Rule | Why It Matters |
|---|---|---|
| Reward basis | Highest reachable stage | Pushing progression raises idle income |
| Accumulation | Capped duration | Claim regularly to avoid wasted time |
| Stage selection | Must clear reliably | Dying repeatedly yields far less income |
| Claim location | Mailbox / idle screen | Rewards wait for you on return |
| Auto-battle | Four heroes, no input | Gear and cards do the work while away |
Before logging off for the night, drop back 2–3 stages from your wall. A stage your party clears 100% of the time generates more total offline income than one where they occasionally wipe.
Offline Setup: Step-by-Step
Follow this routine every time you plan to leave the game running unattended.
Check Your Battle Log
Review recent fights to see which hero is underperforming. An under-geared frontline or support dragging down the party cuts your reliable clear range and directly lowers offline earnings.
Pick a Reliable Farming Stage
Park the party on a stage they clear consistently — not your absolute wall. Offline income is based on sustainable clearing, and repeated deaths waste the entire accumulation window.
Optimize for Clear Speed
Equip speed-oriented gear and cards before logging off. Faster wave clears mean more battles per hour, which compounds into noticeably richer offline rewards.
Claim Rewards on Return
Collect accumulated idle rewards from the mailbox or idle screen as soon as you open the game again, so the accumulation timer restarts without wasted capped time.
Never leave your party parked on a boss wall overnight. Repeated wipes generate minimal offline progress and waste the capped accumulation window entirely.
Best Cards and Builds for Idle Farming
Because your heroes fight automatically, card and build choices determine your offline efficiency more than active play does. Rule-rewriting cards that add actions or guarantee initiative translate directly into faster clears, while economy cards boost every drop earned while you sleep.
Rule Rewrite: Extra Turn
- S-tier for farming
- Chance to act again after attacking
- Multiplies party action economy
- Best on high-damage heroes
Offensive Surge
- Party-wide attack boost
- Faster wave clears
- Core pick for stage pushing
- Pairs well with speed builds
Loot Whisperer
- Economy / farming category
- Boosts gold and material drops
- No combat effect, pure income
- Ideal slot for idle decks
For hero builds, the Gunslinger critical-hit build (Critical Chance, Critical Damage, Attack Speed affixes) is the standout idle pushing setup — it scales damage automatically with no input needed. Guardian Aegis keeps your frontline alive through extended unattended sessions.
| Element | Offline Priority | Notes |
|---|---|---|
| Clear speed affixes | High | More battles per hour while away |
| Extra Turn card | High | More attacks per auto-battle |
| Frontline survivability | Medium | Prevents wipes on higher stages |
| Loot Whisperer card | Medium | Boosts drop income without combat impact |
| Boss-burst builds | Low | Better saved for active endgame play |
If your deck supports flexible slots, swap boss-burst cards like First Strike for economy cards before long offline sessions — the enemies you farm overnight rarely need the initiative advantage.
Offline Income vs. Other Progression Sources
Offline progress is one of several income streams in Undealt, and it interacts with the loot and forge loop. Salvaging the white and green gear your party accumulates overnight into Scrap Metal feeds nearly every early forge recipe — never sell those drops for gold, because the materials are worth far more.
| Income Source | Requires Attention? | Best Use |
|---|---|---|
| Offline idle rewards | No | Overnight and workday baseline income |
| Active stage pushing | Yes | Raising highest reachable stage, boosting idle rate |
| Steam Market sales | Occasional | Trading endgame drops for real value |
| Salvaging offline loot | On return | Converting drops into forge materials |
Offline farming and the Steam Market compound: farm endgame stages with high tradeable drop rates overnight, then check market prices before salvaging anything — some tradeables sell for real value.

Offline Progress FAQ
Q: Does Undealt offline progress keep running when the game is fully closed?
Yes. Undealt continues progressing while the game is closed. Offline rewards are calculated based on your highest reachable stage and accumulate up to a capped duration, so claim them regularly from the mailbox or idle screen.
Q: Which stage should I park on before logging off?
Choose a stage your party can clear reliably — never one where heroes die repeatedly. Dropping back 2-3 stages from your wall usually produces more total offline income than gambling on your hardest stage.
Q: Do cards affect offline earnings?
Yes. Since battles resolve automatically, cards like Rule Rewrite: Extra Turn and Offensive Surge speed up clears, while Loot Whisperer directly increases gold and material drops earned while idling.
Q: Is there a limit to how long offline rewards accumulate?
Rewards accumulate up to a capped duration. Once the cap is reached, additional time away generates no extra income, so claiming rewards when you return and restarting accumulation keeps earnings efficient.
