Portait Upgrade Costs level 1-50
Immortal Portraits in Infinity Kingdom are a pivotal feature introduced in patch 2.6.3, allowing players to enhance their Immortals’ attributes through the use of a resource called Stardust. Upgrading these portraits can significantly boost your Immortals’ combat effectiveness, making strategic investment in this system crucial for competitive play.

Understanding Immortal Portraits
Each Immortal has a unique portrait that can be leveled up to increase their stats. These enhancements include boosts to physical/magical attack and defense, accuracy, dodge, and critical rates, depending on the Immortal’s role (e.g., Tank, Mage, Support). Portait guide video here!
Notably, at certain milestone levels, Immortals receive percentage-based bonuses, which are particularly impactful:
- Level 10: Grants a 5% boost to a specific attribute, varying by Immortal type.
- Level 20: Provides an additional 5% bonus, such as increased physical/magical damage or damage resistance.

These percentage bonuses are substantial and can turn the tide in battles, especially in PvP scenarios. Wiki & Tools | Infinity Kingdom

🎯 Strategic Upgrade Recommendations
Given the escalating costs, it’s advisable to prioritize your Stardust investments:
- Focus on Key Immortals: Invest in your main damage dealers or crucial support Immortals first. Enhancing their portraits to level 20 ensures you capitalize on the significant percentage bonuses.
- Avoid Spreading Stardust Thin: It’s more beneficial to fully upgrade a few key Immortals than to partially upgrade many. This approach maximizes the impact of the percentage bonuses.
- Plan for Milestone Levels: Aim to reach levels 10 and 20 on selected Immortals to unlock the powerful percentage-based enhancements.

This focused strategy ensures that your most impactful Immortals are performing at their peak, providing a competitive edge in battles.
