Upgrade

The Upgrade mechanism enables players to strengthen their assets, including Heroes, Equipment, and Weapons. Each upgrade level and rarity tier requires specific materials and comes with a success rate that fluctuates based on the asset's progression stage, adding an element of strategy to resource management and enhancement.

When an upgrade is successful, the enhanced Hero, Gear, or Weapon gains improved stats, boosting overall combat effectiveness. Higher rarity assets demand rarer materials and come with lower success rates, making strategic resource allocation and risk management crucial for long-term progression.
