What Are The Chances...

They just need to remove this achievement at this point seeing its near impossible now with it always missing

Criteria:
Defeat the Raging Tempest after striking a single player with 5 Lightning Strikes simultaneously and defeating a Storm Elemental in The Nokhud Offensive on Mythic difficulty.

Strategy:
The easiest way to achieve this is by having the tank stand under the boss during Lightning Strike while the other players fan out around them. An add will spawn once the tank has been struck by all five lightning strikes. Simply defeat the add, followed by the boss, and you're finished!

As of patch 11.0 (TWW) this achievement can be very difficult to complete when your party is at level 80.

The spell which the boss uses to apply the lightning strike has a small hit-chance against characters that are above level 70 and misses alot. Getting all 5 people succesfully targeted at the same time requires quite a bit of RNG and can take a long time. We tanked the boss for over 30 minutes and only ever managed to get 4 people hit without the spell missing.

My advice would be to do this with decently geared level 70 characters and it shouldn't be a big issue then.
