What Is Undealt? Idle RPG Overview
Undealt idle RPG is a free-to-play corner-screen idle RPG from developer Tail House, released on Steam on November 12, 2026. Instead of demanding constant attention, a fixed party of four heroes battles automatically while you focus on the strategic layer: managing loot, forging gear, learning skills, and collecting cards that rewrite the rules of combat itself. Two additional DLC characters, Lyriel and Thalen, expand the roster for players who want more direct build options.
The game's core appeal is that it rewards optimization between fights, not reflexes during them. Your job is to read the battle log, spot which hero is underperforming, and adjust their gear, skills, and cards accordingly.

The Four Heroes and When They Peak
Because the party is fixed at four heroes, tiering in Undealt is less about who to pick and more about when to invest in each hero. Early game favors raw damage to push stages fast, mid game rewards frontline durability, and late game the support's scaling buffs become decisive.
| Hero Role | Early | Mid | Late | Investment Priority |
|---|---|---|---|---|
| Main DPS | S | S | S | First — weapons and damage skills |
| Frontline Tank | B | A | S | Second — armor forging once damage stalls |
| Ranged DPS | A | B | A | Third — second weapon upgrades |
| Support / Healer | C | B | S | Steady, not heavy, early investment |
Do not pour enhancement materials into common or low-rarity gear early on. Save them for equipment you will keep across multiple stages — replacing upgraded commons wastes scarce forge materials.
Two DLC characters add playstyle variety: Thalen, a druid who can transform and copy enemy attacks, and Lyriel, who brings her own skill set and party role. Both are optional and tuned as sidegrades rather than strict upgrades to the core four.
Beginner Progression: Step-by-Step
Follow this order in your first few sessions to build a smooth progression loop from day one.
Understand Auto-Battle
Watch battles resolve and check the battle log. Identify which hero dies first or deals the least damage — that is your first fix. Each hero has a distinct role, and your job is loadout optimization, not combat input.
Set Up Offline Earnings
Offline rewards are calculated from your highest reliably clearable stage and accumulate up to a capped duration. Before logging off, park your party on a stage they clear consistently, not one where they wipe.
Sort Your Loot
Equip pieces with the correct main stat for each role, salvage white and green gear into materials, and sell the leftovers for gold. Never sell Scrap Metal — it feeds nearly every early forge recipe.
Forge in the Right Order
Forge weapons for your two damage dealers first, since faster clears raise all income. Then armor for the frontline, then support gear. Spread forges evenly only after everyone has a baseline set.
Learn Skills Efficiently
Take core damage skills for your main DPS, survivability for the frontline, then healing and buffs. Unlock each hero's full basic kit before deep-specializing for a bigger early power spike.
Once your main DPS has a maxed core damage skill and a forged weapon, you have escaped the fragile early phase — from here, prioritize frontline armor to unlock higher stages.
Cards: Rewriting the Rules of Battle
The card system is Undealt's signature mechanic. Cards are earned through stage progression, chests, and events, and slot into a shared deck whose effects apply to every battle. The strongest cards do not just add stats — they rewrite combat rules themselves.
| Card | Category | Effect | Rating |
|---|---|---|---|
| Rule Rewrite: Extra Turn | Rule Rewriting | Chance for heroes to act again after attacking | S |
| Rule Rewrite: First Strike | Rule Rewriting | Party always acts first each wave | S |
| Offensive Surge | Damage Boost | Party-wide attack power increase | A |
| Guardian Aegis | Defense / Sustain | Damage reduction plus frontline shielding | A |
| Loot Whisperer | Economy / Farming | More gold and material drops | B |
Rule Rewrite: Extra Turn multiplies your action economy and pairs best with high-damage heroes — treat it as the default first pick for stage-pushing decks, then add sustain or farming cards to match your goal.
Cards also interact with skills and gear affixes. For example, the Gunslinger's Dead Eye skill multiplies with crit damage affixes and the Lucky Streak card, while Trickster builds cycle cards endlessly by stacking Sleight of Hand with Recycle. Always evaluate a card by how it compounds your existing build, not just its standalone text.
Loot, Forge, and the Steam Market
Undealt separates its economy into three layers: what drops, what you craft, and what you can sell for real value.
| Decision | Item Type | Best Action |
|---|---|---|
| Loot | White / Green gear | Salvage — selling yields almost nothing |
| Loot | Blue / Purple gear | Keep only correct main stat pieces, salvage rest |
| Loot | Tradeable drops | Check Steam Market price before salvaging |
| Forge | Gear upgrading | Duplicate pieces + Scrap Metal to raise item level |
| Forge | Affix rerolling | Cursed Essence on rare+ items with good bases only |
| Materials | Cursed Essence | Reserve for high-tier crafts, never low-level rerolls |
Never undercut aggressively. Crashing a price hurts your future drops too. Price slightly below the lowest sell order for fast sales, sell in small batches, and hold inventory during new-content hype windows to sell into demand spikes. Remember that Steam's transaction fee applies to every sale.
The most reliable profit loop is farming endgame stages with the highest tradeable drops per hour, using an idle build tuned for stage-clear speed rather than boss burst. Track drops per hour, convert to expected market value, and switch stages when the math favors another route. Diversify what you farm so a single price crash does not wipe out your income.
First Week Goals
Essential First-Week Milestones:
- Unlock full basic skill kit for all four heroes
- Forge weapons for both damage dealers
- Park overnight farming on a reliably clearable stage
- Draft one Rule Rewrite card into your deck
- Check Steam Market prices before salvaging any tradeable drop
By end of week one, pick a build direction per hero — crit stacking for Gunslinger, counterattack for Bruiser, card-draw engine for Trickster — and commit forge materials toward its core affixes instead of splitting resources.
FAQ
Q: Is Undealt idle RPG free to play?
Yes. Undealt launched free on Steam on November 12, 2026. Optional paid content includes two playable DLC characters, Lyriel and Thalen, alongside the free four-hero core roster.
Q: Does Undealt progress while the game is closed?
Yes. Offline rewards are calculated from your highest reliably clearable stage and accumulate up to a capped duration. Park your party on a stage they clear consistently before logging off, then claim rewards from the mailbox or idle screen.
Q: How do rule-breaking cards work in Undealt?
Cards slot into a shared deck that applies to every auto-battle. Rule-rewriting cards change how battles resolve — for example, granting extra actions after attacks or making your party always act first — effectively flipping matchups that raw stats would lose.
Q: Can I earn real money from Undealt?
Certain endgame drops are tradeable on the real Steam Community Market and sell for Steam Wallet funds. Regular leveling loot is account-bound, so always check the item tooltip for the tradeable icon before salvaging.
