The Thunder Firefly in Summons of the Seven Saints in "Genshin Impact" is a strategy card, which is closely related to the Thunder Firefly Warlock character in the game. The following is an introduction to the basic information of Lei Ying Fu Shan:
【Thunder Fireflies Floating】
Combat Action: When our combat character is Fools and Fireflies Warlock, equip this card.
After the Fools and Thunder Fireflies equip this card, they immediately use the Call of Mist Void once.
When the Fools and Thunder Fireflies equipped with this card are on the field, before we choose to act: If the number of available Thunder Fireflies is at least 3, the Thunder Fireflies will immediately cause 1 point of thunder element damage. (Requires consumption of available times, 1 time per round)
(The deck can only be added if the deck contains Fools and Fireflies Warlock)
