Own it. Develop it. Deploy it.
Testnet notice
Battle of Doragon is in active development. $DTF, $CROWN, and the reward parameters described here are currently Base Sepolia testnet systems and may change before mainnet.
The big picture
Start here
Kojin is the connective layer between character ownership, progression, strategy, and rewards. Your Kojin is not just a profile image—it can work in your city, command an army, grow stronger, and improve how you participate in the game economy.
Competitive utility
Power strengthens $CROWN rewards
Compete for territory to earn Crown Shards. At settlement, total eligible Kojin Power determines the multiplier used by the Crown Forge.
Territory→Shards × Power→$CROWN

Playable ownership
The role of Kojin
Kojin are onchain dragon characters that carry identity and utility across the ecosystem. Their traits, House, rarity, level, equipment, Stars, and Power shape what they can contribute in Battle of Doragon.
Identity
A persistent character with a unique appearance, House, traits, ownership history, and progression.
Commander
Deploy a Kojin with an army. Commander Power contributes directly to the force you bring to a fight.
Manager
Assign Kojin to eligible city buildings for management boosts and active Star contribution.
Progression
Raise level and rarity, equip six gear slots, enhance equipment, complete trials, and promote.
Economy
Stars support building boosts and improve Dragon Fruit processing, connecting active play and city planning to $DTF.
Rewards
Total eligible Power improves the Crown Forge multiplier applied to earned Crown Shards.
Free-to-play access: Battle of Doragon includes a universal starter Kojin so players can enter the core loop. Owned Kojin expand collection choice, specialization, progression, and utility.
Production path
Stars, Dragon Fruit, and $DTF
Stars are the economic-output side of Kojin utility. They do not create tokens passively: players must gather Dragon Fruit, assign eligible Kojin, and complete the processing loop.
01 · Gather
Dragon Fruit Grove
02 · Return
Raw Dragon Fruit
03 · Process
The Juicery
04 · Claim
$DTF
- 01
Harvest Dragon Fruit
Find finite Dragon Fruit Groves on the world map. Fruit is credited only after the gathering march safely returns to your city.
- 02
Assign Kojin managers
Place eligible Kojin in constructed city buildings. Newly assigned managers must remain in place for a complete processor cycle before their Stars become active.
- 03
Process at the Juicery
The Juicery consumes account-bound Dragon Fruit and calculates output from eligible active Stars.
- 04
Claim $DTF
A replay-protected settlement authorizes the corresponding testnet $DTF claim to the player’s game wallet.
- 05
Use $DTF for breeding
Dragon Transformation Fluid is Kojin’s breeding cryptocurrency and is designed as a consumable input to creating the next generation of Kojin.
Offchain
Dragon Fruit
Account-bound raw material earned through gathering.
Kojin utility
Stars
Active manager contribution that improves processing output.
Onchain
$DTF
An ERC-20 breeding currency currently deployed on Base Sepolia.
Competitive path
Power, Crown Shards, and $CROWN
Power represents developed strength. It supports combat and guild competition, then gives long-term Kojin progression an economic role when Crown Shards settle through the Crown Forge.
Power grows through
Develop your Kojin
- Kojin level and rarity progression
- Equipped gear and enhancements
- Equipment evolution and set choices
- Completed trials and promotion tiers
Crown Forge formula
Shards × Power = $CROWN
Your territory activity earns Crown Shards. When the contest cycle ends, the Crown Forge uses your eligible Kojin Power multiplier to determine the testnet $CROWN conversion.
Power does not generate $CROWN by itself. Territory participation supplies the Crown Shards that Power multiplies.
Guild warfare
Compete for territory
Territory is the competitive center of the world map. Guild members dispatch armies, contest control, hold strategic nodes, and build contribution time toward seasonal rewards.
5
Imperial Wards
The claimable territories surrounding the Imperial Dragon Monument.
3
Wards to rule
Control at least three Imperial Wards to become Emperor of the center.

Quick answers
Frequently asked questions
The shortest answers to the questions players and collectors ask most often.
What role does the Kojin NFT play?+
It is the utility and progression layer: Stars support boosts and $DTF production, while Power strengthens gameplay, territory competition, and the Crown Forge multiplier used for $CROWN rewards.
