The White Phosphor Lake is a Scenic Viewpoint in Xenoblade Chronicles X. It is located in western Cauldros, north of the Emerian Battlegrounds and surrounding FN Site 503. It is most notably inhabited by several Phosphorous Filiavents and the Tyrant Trueno, the Cataclysm, who guards a teleporter. The lake itself should not be stepped in, and deals 1200 damage in the same manner as lava. Lulladu can be found here during Gorkwa Games, as can Kiliran during The Old Gods. As with all Scenic Viewpoints, its discovery yields an achievement ("The Glow of White Phosphor Lake").
