In Rogue Roll Ruler’s, players will progress through their adventures using three types of NFTs:

  • Adventurer NFTs: These NFTs serve as the players’ strength and are used to form parties for conquering dungeons. There are adventurers skilled at repelling monsters, and adventurers skilled at efficiently advancing through the dungeon.
  • Equipment NFTs: These are equipment items that adventurers can equip. They cannot be purchased on the market, but can instead be obtained by exploring dungeons. Discover rare and powerful equipment to strengthen your adventurers.
  • Monster NFTs: While these monsters obstruct the path, it will be possible to hinder other adventurers by making them allies. (Note: Implementation of monster NFTs is planned after the game’s launch.)

■Comment from Yuma Ito, Directpr of Rogue Roll Ruler’s

When I first learned about Play-to-Earn and blockchain games, I was immediately captivated by the idea of “earning while playing games.” If we’re going to do something, why not have fun and earn a lot in the process? I thought it would be interesting to have moments where luck is on your side and you can earn a substantial amount. With that in mind, I consolidated the ideas for this game.

Rogue Roll Ruler’s not only focuses on the “earning” aspect, but also incorporates the enjoyment of discovering, combining and deciphering the story woven into the game. I want players to experience the excitement of finding treasure before anyone else and set their desired selling prices, enjoying the thrill of whether they sell or not.


■Regarding the NFT Pre-Sale

In August, DEA will conduct a pre-sale of NFTs on the “PlayMining NFT” marketplace. The NFTs available for pre-sale are Adventurer NFTs that provide advantages in progressing through the dungeon. Among them, the following adventurer NFTs are powerful ones that can give you an advantage in battles. They have high rarity and possess strong skills, making them excellent NFTs for a quick start!


 ・Flagbearer Latria

This adventurer possesses well-rounded skills and stable strength, making them easy to use overall.


 ・Sage hah_yahga

This adventurer has slightly skewed stats and skills that prioritize firepower, albeit randomly.
