🔁 Item Upgrade

Upgrade items by combining 10 of the same quality to create a higher-tier item. Enhance your combat and productivity.

Upgrade Materials

• Social Items max out at R-tier

• Heroes & Weapons can be synthesized up to G-tier

Upgrade Rules

1. Basic Upgrade Rules

Material Requirements:

• Each upgrade requires 10 items of the same rarity (or a combination with Upgrade Seeds).

• Upgrade Seeds can be used as substitute materials to help reach the required amount more flexibly.

Upgrade Rarity Outcome:

• The resulting item will be one rarity tier higher. For example, 10 R-rarity items can be synthesized into 1 SR-rarity item.

• Heroes and weapons can be synthesized up to G-rarity. Social items can only be synthesized up toR-rarity.

2. Upgrade Probability

Standard Materials: Each standard item contributes 10% success rate.

Upgrade Seeds: Each seed contributes 8% success rate, slightly lower than standard items.

3. Upgrade Seeds

Creation Method: Players can synthesize 1 R-rarity Upgrade Seed by combining 10 R-rarity social items (emotes or actions).

Usage Rules: Upgrade Seeds can replace items of the same rarity, offering flexibility when materials are insufficient.

4. Priority Hero Mechanism

Priority Inheritance Rules: If any Priority Heroes are included in the upgrade materials, the resulting hero has a chance to inherit the Priority status. The inheritance chance equals the number of Priority Heroes used × 10%. (1 Priority Hero = 10% chance, 2 Priority Heroes = 20%, and so on.)

Random Hero Selection Rules: The system will randomly select one of the 10 input heroes as the result. The resulting hero will inherit all attributes (such as combat stats and talents) from the selected hero — only the rarity is upgraded. If the Priority attribute is inherited, the selected hero will become a Priority Hero.

5. Upgrade Restrictions

Same-Rarity Only: Only items of the same rarity can be used in a single upgrade. For example, R-rarity items can only be synthesized with other R-rarity materials or R-rarity Upgrade Seeds. Cross-rarity combinations are not allowed.

Upgrade Zone Rules: You cannot use only Upgrade Seeds in the upgrade interface. At least one real item is required to proceed with upgrade.

📌Heroes, weapons, and other items must all be inactive to be used for Upgrade. Please make sure they are removed from deployment or usage status before proceeding.

Upgrade Example: Priority Hero Upgrade

Materials:

• 6 R-rarity Heroes (including 1 Priority Hero)

• 4 R-rarity Upgrade Seeds

Success Rate Calculation:

• (6 × 10%) + (4 × 8%) = 60% + 32% = 92% total success rate

Priority Inheritance Probability:

• With 1 Priority Hero used in the materials, the chance to inherit Priority status is 10%.

If Upgrade is Successful:

• The system will randomly select one of the 6 input R-rarity Heroes and upgrade its rarity to SR.

• If the Priority inheritance succeeds, the selected SR Hero will gain Priority status.

• The remaining 5 R-rarity Heroes and all 4 Synthesis Seeds will be consumed.

• The resulting Hero will retain the talents of the randomly selected hero.
