*Isekai Battle has migrated to Ethereum L2 Chain Optimism on Jun. 28, 2024 due to the rising gas fees.

Story

Hundreds of years have passed since the war of the gods ended. The people of Turkenista were beginning to return to their peaceful lives.

This is Halnearth in the far east of Turkenista.

A torn book is found in a shrine said to be an ancient ruin.

The Book of Rein, Chapter of Truth, Verse 14.

This was the name given to the pages which contained a map of what seems to be Halnearth and words that no one could read.

- When the seven Fragments come together The lost power of the gods will be revived and unleashed -

The one to decipher the words was from another world.

Each character has a favorite Weapon “Sword, Two Hands, Fists, Bow, Staff” and Armor “HeavyArmor, LightArmor, Robe”. By matching their favorite equipment, the Weapons and Armor that are equipped to the troops led by the Character will get a stat boost during Battles.

cf.Battle - Unit power

Character stats

ATK: Every 1 point increases the bonus rate of their favorite weapon by 0.5%.

DEF: Every 1 point increases the bonus rate of their favorite armor by 0.5%.

LUK: Every 1 point increases the chances of finding “Seeds” through Exploration.

Weapon/Armor stats

Lv1 stats have an expected value of 10 for attack/defense power(the value will be randomly chosen between 5 - 15)

Lv2 stats have an expected value of 25 for attack/defense power (the value will be randomly chosen between 17 - 33)

Lv3 stats have an expected value of 50 for attack/defense power (the value will be randomly chosen between 40 - 60)

*The random value range, etc., is subject to change.

The definition of Character ID and generation (GEN)

GEN0 : ID 1 - 5500

GEN0.5: Character ID above 5501 with 0 as the last digit.

GEN1 : Character ID above 5501 with 1-9 as the last digit.

*ID 1 - 150 will be managed by the operation team for distribution purposes in events.

Special bonuses depending on generation (GEN)

GEN0 : The cost to fuse and use Seeds is reduced by 10%.

GEN0.5 : The cost to fuse and use Seeds is reduced by 5%.

*The reduction for using Seeds only applies to that Character, and the reduction for fusing Seeds will be applied by owning 1 character. (The reduction will not pile up and the maximum is 10%)The reduction rate is subject to change.

Exploration

Select a region on the world map to go on an Exploration. You can find Weapons/Armor/Seeds/Fragments(after implemented), and you will need to claim them at the end of your Exploration. The more Characters you have going on an Exploration, the higher your chances are to find each item, and higher level Weapons/Armor. (Weapons/Armor/Seeds will not be taken by other players)

Weapons/Armor

They are items needed for the Battles for NFTs. The Weapons will be automatically equipped to all troops led by the Characters set in the Attack Unit and the Armor to the troops led by the Characters in the Defence Unit. For example, if there are 100 troops in the unit, 100 Weapons/Armor will be equipped automatically with priority to the Character’s favorite equipment and higher level. The total of each stat will be the Unit’s “attack/defence power”. Also, when the Weapons/Armor match the Character’s favorite equipment, there will be a bonus stat boost. Weapons and Armor will break at a certain rate after battles, so once in a while, you will need to find more by going on Explorations.

cf.Battle - Unit power

*You can only hold 200 pieces of Weapons/Armor. We are considering a system that would allow you to increase the limit in the future. *When Weapons/Armor are bought/sold/through secondary trade, they will be locked for 48 hours.

We have a new collection due to migrating to Optimism.

Seeds

  • You can find Seeds when you have 3 or more Characters going on an Exploration in the world map.

  • The total LUK of the Characters Exploring the world map determines the rate to find Seeds.

  • There are 3 types of Seeds: “ATK Seed”, “DEF Seed”, and “LUK Seed”.

  • ETH will be consumed to fuse and use Seeds.

  • Each Character can be fed a maximum of 10 Seeds. (when the Characters are given their first SEED, their levels will increase from 1 to 10)

Fragment(NFT)

  • They will be available through Exploration and Battles after being implemented.

  • Each region has a different series of Fragments (NFT).

  • Each region has 7 Fragments, and each Fragment has a different total supply.

  • Only 1 Fragment (NFT) per Character can be claimed through a single Exploration. Having more Characters going on an Exploration will increase your chances of finding them.

  • There is a limit to how many Fragments you can find from Explorations.

Battles

The Battles are PVP battles in which you fight other players for Fragments (NFT). You can take Fragments (NFT) that you don’t own from other players, but you’re Fragments (NFT) are also at risk of being taken by other players. The balance between the Attack Unit and Defence Unit is crucial.

Battle flow - Attack side

  1. Organize the Attack Unit

  2. Select the Fragment you want to target.

  3. Attack a player who has the Fragment you want.

  4. Your attack power and the other player’s defence power are compared in the Battle.

  5. If you win, you take the other player’s Fragment, and if you lose, you get nothing.

Battle flow - Defence side

  1. Organize the Defence Unit

  2. Other players will attack you (Battles can happen when you are not playing the game)

  3. Your defense power and the other player’s attack power are compared in the Battle.

  4. If you win, you defend your Fragment, and if you lose, you lose it.

*Weapons/Armor will be lost in the Battle regardless of whether you win or lose. Weapons/Armor can be restocked by going on Explorations.

*Even if you lose the Battle when you attack another player, you will not lose Fragments (NFT) you own.

Unit power - Overview

The power of the Unit is calculated for each battle based on the number of troops in the Unit, equipment collected through Exploration, and Character traits.

Unit power - Number of troops

The player has 30 troops each in the Attack Unit and Defense Unit, and the Characters each have 10 troops under their command.

e.g. When attacking Player + 3 Characters →30+10*3=60

Unit power - Equipment and Character traits

During the battle, the strongest "Weapon" for attacking and the strongest "Armor" for defending are automatically equipped, based on the combination of equipment acquired in Exploration, in relation to the number of troops in the Unit. The attack and defense power are multiplied by a bonus factor depending on each character's trait (Sword, HeavyArmor, etc.) and the number of Weapons/Armor to which they respond. (If you have 100 Weapons in your Inventory when attacking and the number of troops is 73, 73 Weapons that will make your attack power the highest will be automatically equipped)

Details - Fragment(NFT)

Fragments (NFT) will be available through “Exploration” and “Battles”. Each region has its own series of Fragments (NFT) you can find.

*Fragments are NFTs but cannot be bought, sold, or transferred.

Obtaining through “Exploration”

Check Exploration - Fragment (NFT)

Obtaining through “Battle”

There is a limited supply for each Fragment (NFT), and when all Fragments are found through “Exploration”, you can only get them through “Battles”.

The Battles are PVP battles over Fragments (NFT).

You can get a SINKI (NFT), which releases SINN (ERC20), by completing a series of 7 Fragments (NFT) from a region.

Power up your Characters and organize the best Units to collect Fragments (NFT) and get your hands on SINKI!

Completion and SINKI acquisition

By collecting all 7 Fragments of a region, they begin to resonate. “Break the Seal” to restore the SINKI (NFT) and release SINN (tokens).

Details - SINKI(NFT)

SINKIs can be restored by Breaking the Seal after collecting all 7 Fragments of a region, or purchasing them secondhanded from OpenSea, etc.

SINKIs contain SINN (ERC20), but it is released gradually, so it takes a while to collect all the SINN. (After the SINN is all released, the SINKI becomes empty and you will not be able to get any more SINN)

*SINKIs (NFT) cannot be taken by other players through “Battles”.

Details - SINN(ERC-20)

SINN (ERC20) are in-game tokens that are released gradually from SINKI (NFT) over a period of time.

Details - Seed fusion

The Seeds found through Explorations can be fused into more effective Seeds by using ETH. The more Seeds you fuse, the better their effect becomes, but the cost will also increase.

ex.

“ATK Seed” + “ATK Seed” + ETH =“ATK Seed Lv2-3” “ATK Seed” + “ATK Seed” + “ATK Seed” + ETH =“ATK Seed Lv3-5” “ATK Seed”× 4 + ETH = “ATK Seed Lv4-6” … … “ATK Seed”× 8 + ETH= “ATK Seed Lv8-10”

*The specification of fusing is subject to change. *The ETH consumption depends on the GEN of the Character you selected when fusing Seeds. cf. The definition of Character ID and generation (GEN)

Details - Magic Circle NFT

By owning a Magic Circle NFT, the chances of getting a bonus on the Seed fusion result will increase. Having multiple of them will increase the chance even more.

*The actual increase rate will be announced when the Seed fusion is implemented.

The number of Magic Circle NFts and the chance of getting a bonus on the Seed fusion

0 Magic Circle NFTs|No bonus: 70% |+1: 20%|+2: 10% 1 Magic Circle NFT |No bonus: 50% |+1: 30%|+2: 20% 2 Magic Circle NFTs|No bonus: 30% |+1: 40%|+2: 30% 3 Magic Circle NFTs|No bonus: 10% |+1: 50%|+2: 40% 4 Magic Circle NFTs|No bonus: 0% |+1: 50%|+2: 50% *Owning more than 4 Magic Circles will not change the bonus effect.

Changes upon migrating from Ethereum to Optimism

  • Probability of obtaining a Seed per LUK point: +0.1% → +0.125%

  • Maximum number of Weapons/Armor: 120 → 200 *If the total LUK value of the Exploration Unit is 32, the probability will be the same as the Ethereum version.

  • Seed Claim cycle: approx. 7 days (167h) → approx. 3 days (71h)

  • Probability of obtaining a Seed with 5 or more Characters on Exploration: 5% → 1%

  • Expected number of Seeds obtained with 15 Characters on Exploration: 0.75 → 0.15

Token economics
