Genshin Impact players eagerly awaiting the 5.4 update can currently exploit a surprising game mechanic to effortlessly defeat even the toughest bosses. This exploit, ironically, utilizes the Hydro Traveler, often considered a weak DPS character.
The method is deceptively simple. Using the Hydro Traveler's Elemental Burst in conjunction with Xiao Lanterns (obtained during the Lantern Rite Festival) creates a powerful effect. Placing numerous lanterns near a boss and activating the Elemental Burst results in massive AoE damage, significantly depleting the boss's health. The burst's damage is amplified by its interaction with the lanterns; hundreds of lanterns can yield millions of damage points.
While this exploit is expected to be patched in a future update, it currently provides a remarkably easy way to overcome challenging boss encounters.
