The trial of Yu'lon is a test of wisdom and faith. With omens of a bleak future floating through his mind. Emperor Shaohao climbed to the summit of Mount Neverest to seek the council of the Jade Serpent. Yu'lon urged Shaohao to cast off the dark emotions that plagued him, and through his trials, Emperor Shaohao would becone one with the land. To pass the trial of the Serpent, warriors must be wise in their choices.

Yu'lon is generally seen as the most difficult of the four celestials, with high amounts of both tank and raid-wide damage, along with a deadly and hard to dodge mechanic in Jadefire Wall. Only one tank is required.
The tank may attempt to dodge Jadefire Breath by moving to either side while Yu'lon is casting. The Jade Serpent will periodically shoot Jadefire Bolts to the ground around her, creating Jadefire Blazes. These blazes can be somewhat hard to see against the green-brown ground of the arena, particularly when the graphics settings are on low. In addition, they spawn quickly with no cast time and little warning, so raid members should always be ready to move. The tanks should constantly be kiting Yu'lon around the arena to minimize threat of the Jadefire Blazes. While kiting, keep Yu'lon faced away from the raid to avoid damage from Jadefire Breath.
The Jade Serpent's most devastating attack is Jadefire Wall, summoning a giant wave of green fire that starts at the end of the arena where Emperor Shaohao is. The mechanic is similar to Sartharion's Lava Walls, with small gaps in the waves as the only way to avoid them. For this reason, the tanks should try to keep the combat to the other side of the arena to give the raid as much time as possible to get between the gaps.
