• Healing builds for damage-dealing champions can pair Echoes of Helia with Protein Shake or Critical Healing; Ezreal and Bard are examples.⁵
• A healing build can start with Sword of Blossoming Dawn and Echoes of Helia, then use tank items to stay alive and keep healing. It also calls for a prismatic augment with heal or shield power, Angel of Retribution, and Protein Shake.⁶
• A team build can use three Sword of Blossoming Dawn items alongside Echoes of Helia. Xayah is recommended for her high attack speed ratio, with Firebrand for damage and attack speed modifiers.⁷
• A Singed build can use Liandry's, Echoes of Helia, Staff of Flowing Water, Moonstone, and Abyssal Mask.⁸
• Pair Dusk and Dawn, Sword of Blossoming Dawn, and Echoes of Helia; Fan the Hammer brings the build to full power, though other on-hit augments also work.⁹
