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 remarkably straightforward. By strategically placing numerous Xiao Lanterns (obtained during the Lantern Rite Festival) near a boss, and then activating the Hydro Traveler's Elemental Burst, a massive amount of AoE damage is inflicted. The interaction between the Burst and the lanterns causes unexpectedly high damage, potentially reaching millions with a sufficient number of lanterns.
This exploit's effectiveness stems from the Elemental Burst's amplified AoE damage when interacting with objects. While undoubtedly a temporary glitch, it currently provides a remarkably easy way to overcome challenging boss encounters. Expect this exploit to be patched in a future update.
