In Blue Protocol, weapons and IMAJINN provide attributes for player characters to enhance the player's combat effectiveness. In Blue Protocol, players strengthen their characteristics by creating high-rarity weapons and collecting IMAJINN, which are used to attack dungeons. They can improve their character and adventure levels to explore a wider area.

Due to the huge upper limit gap between low-rarity and high-rarity weapons, players will seek to acquire more high-rarity weapons as soon as possible to experience more game content.

However, forging high-rare weapons requires a coupon to increase the chance of successfully developing and preparing various monster materials.
