There's no need to freak out. This is a patch on Blight, after all, and we created this thread for the very purpose of getting feedback on the issues. We can adjust the Fyakki spawn again and we're going to be adjusting the cost of the Loyalty vaults down significantly.
Regarding Crystalshaper, Indestructible Fyakki can be gathered from using any of the Tier 6 Inspire abilities.
