Foul Legacy Childe

"Foul Legacy: The Devouring Deep" (From the game "Genshin Impact"). This transformation  is a combat technique utilized by Childe (Tartaglia). While under the effects of Foul Legacy Transformation, Tartaglia is able to wield the powers of his hydro vision and electro delusion at the same time. However, using this ability is extremely draining on him and has lasting repercussions on his body. This power does not originate from his Delusion; he learned it from Skirk after he fell into the Abyss, before he joined the Fatui, with the transformation receiving its name from Surtalogi "The Foul", Skirk's own master.
