I am near the end of Stormblood, and have a full set of 90 crafters. I was able to get books 1-8 before finishing HW, but it seems book 9 might be gated? That or I am doing something wrong.

Patch notes only say 6.x is needed, they don't list any quest pre-requisites, yet this is what I see...




So far I have checked the Scrip exchange in Grid, Mor Dhonuts, and Rhalgr's Reach, all end at book 8.

Does anyone have any idea what the unlock is? Shadowbringers, or do I need to rush to Endwalker to make anything with level 90.
