Genshin Impact players eagerly awaiting the 5.4 update can currently exploit a surprising tactic to effortlessly defeat even the toughest bosses. This unexpected strategy utilizes the Hydro Traveler, often considered a weak DPS character, to dramatically reduce enemy health.
The method is surprisingly straightforward. It involves placing a significant number of Xiao Lanterns (obtained during the Lantern Rite Festival) near a boss. Activating the Hydro Traveler's Elemental Burst then triggers a massive AoE damage increase due to the interaction with the lanterns. With a sufficient number of lanterns (around a hundred), damage output can reach millions, effectively decimating the boss's health bar.
While this exploit is likely to be patched in a future update, it currently provides a remarkably easy way to conquer challenging boss encounters.
