Lei Shi only really has one phase and rotates the abilities used.
KILL AN ELEMENTAL
TO BRING DOWN THE SHIELD
At 80%, 60%, 40% and 20% health remaining, Lei Shi surrounds herself with an impenetrable bubble and summons several elementals to protect her.
The bubble remains until one of the elementals is defeated. One Elemental should be marked and focused on to end this phase as fast as possible.
DPS THE BOSS
TO STOP THE PUSHBACK
FIND LEI SHI
WITH AOE ABILITIES
Usual melee attacks are replaced by Spray and target the Tank.
There is a 2.5 yard splash on this ability, so the Tank must stand by themself.
Spray does moderate Frost damage and increases Frost damage taken by 10%.
Tanks should aim to swap at around 10 stacks.
