Genshin Impact Jadefall's Splendor Weapon

For 3s after using an Elemental Burst or creating a shield, the equipping character can gain the Primordial Jade Regalia effect: Restore 4.5 Energy every 2.5s, and gain 0.3% Elemental DMG Bonus for their corresponding Elemental Type for every 1,000 Max HP they possess, up to 12%. Primordial Jade Regalia will still take effect even if the equipping character is not on the field.
