Genshin Impact players eagerly anticipating the 5.4 update can currently exploit a surprising game mechanic to effortlessly defeat even the toughest bosses. Paradoxically, this exploit utilizes the Hydro Traveler, a character often deemed a weak DPS option.
The exploit's simplicity is deceptive. Without delving into the game's code, the process involves the Hydro Traveler's Elemental Burst and Xiao Lanterns obtained during the Lantern Rite Festival. By strategically placing numerous Xiao Lanterns near a boss and activating the Elemental Burst, the boss's health dramatically depletes.
This occurs because the Elemental Burst's AoE damage is amplified when interacting with objects. Deploying a large number of lanterns (hundreds, for instance) can result in millions of damage points.
While this exploit is almost certainly slated for a future nerf, it currently provides a remarkably easy path to conquering challenging boss encounters.
