Building characters like Herta and Lingsha efficiently in one stream can be quite rewarding once you understand how to optimize their stats and set effects properly. From my experience, focusing on key stats such as HP Percentage, CRIT Rate, CRIT Damage, and Break Damage significantly boosts overall performance. For example, equipping 2-piece sets that increase Break Damage by 16% can dramatically affect your damage output, especially in critical moments. Additionally, increasing CRIT Rate and CRIT Damage stats not only enhances your damage but also helps in triggering super break damage when needed. Don't overlook the importance of speed (SPD) and defense (DEF) stats — they contribute to your characters' survivability and action frequency during battles. Random stat enhancements can be a game-changer if you get lucky with bonuses like HP or ATK Percentage. In my builds, I also pay attention to the synergy between set effects and stat boosts because balancing these properly allows for more versatile and powerful gameplay. Overall, taking the time to carefully select and upgrade your gear during a stream pays off and elevates the gaming experience in #HSRxFortnite.
