About DmonMaster
DmonMaster drops you into DREAL, a world inhabited by 100 distinct beings called Dmon. Your goal is to gather each Dmon by conquering the Domains they rule, eventually becoming the DmonMaster.
The game runs at your own pace with a Mouse Only option, features no grinding, experience, or skill‑point systems, and lets you watch 3v3 auto‑battles after assembling your Dmon deck.
01 / THE GUIDE
Collecting Dmon
The primary objective is to locate all 100 Dmon spread across the game's Domains. Each Domain is governed by a Dmon; defeating the Domain’s battle adds that ruler to your collection.
When a new Dmon joins you, it is ready for battle immediately, allowing you to test its abilities in the next Domain without any leveling or preparation.
- Note which Domains you have cleared to avoid repeating battles.
- Observe early Dmon abilities to spot natural synergies.
02 / THE GUIDE
Deck Building
Your deck consists of a chosen trio of Dmon, each offering a unique ability. Selecting Dmon whose abilities complement each other forms the core of strategic depth.
Because every Dmon is battle‑ready, you can rearrange your trio after each encounter, using trial and error to discover stronger configurations.
- Mix contrasting abilities to cover varied combat scenarios.
- Keep a backup trio to compare performance after changes.

03 / THE GUIDE
Auto‑Battle System
Battles are 3v3 auto‑battles; after you pick your three Dmon, the combat runs without further input, letting you watch the outcome from a distance.
Strategic influence comes from pre‑battle deck composition, as the Dmon act independently during combat and no real‑time commands are required.
- Watch battles to see which abilities triggered.
- Adjust your trio based on the opponent’s known Dmon lineup.
04 / THE GUIDE
Dvice Equipment
Dvice are pieces of equipment that can be assigned to Dmon. Winning battles grants you chances to obtain new Dvice, including ultra‑rare variants.
Equipping a Dmon with a Dvice provides an additional layer of customization; the exact impact varies, so testing different pairings is encouraged.
- Try the same Dvice on multiple Dmon to gauge its effect.
- Prioritize rare Dvice for Dmon that already fit your core strategy.
05 / THE GUIDE
Pace and Input
DmonMaster is a single‑player title that runs at your own speed; there is no timed input, and a Mouse Only option lets you navigate menus and select Dmon without a keyboard.
Steam Cloud keeps your progress saved, and Family Sharing is supported, while the lack of grinding lets you focus on strategic experimentation.
- Use the mouse to quickly swap Dmon in the deck screen.
- Enable Steam Cloud to preserve your collection across installations.
