Rumors of Xilonen being a universal Support in Genshin Impact might be true after all, as a recent leak reveals the powerful bonus that her second Constellation will bring. While Genshin Impact tends to frown upon power creep, every once in a while, a truly transcendent character makes a debut that completely turns the meta upside down. For Sumeru, this was Alhaitham; for Fontaine, it was Neuvillette. While the jury is still out for Natlan, all signs heavily point towards Xilonen being the one.
