So... what about the Behemoth FATE ?

[Jojoya]

Yep, only issue about Coeurlregina is that the first of the 3 FATEs starts with killing trash, so it's a lot less visible

The first FATE is always right outside Tailfeather so it's easy enough to find if you notice the weather change. Second one is either outside Tailfeather or about halfway between Tailfeather and Loth ast Vath.

If the sky is green for Royal Levin, it is either the first or second FATE. The sky will be red during Royal Levin for the achievement FATE.
