Hey folks, apologies for the delay.
Speaking with the team the buff is working as intended as it does function in raids and is consumed. The issue arose from some patch notes getting merged and left in the wrong section.
We have since updated the patch notes to better reflect the raids changes.
- The drop rate of Achto armour in raids is no longer bound to owning the normal armour sets.
- Developer note: Previously players who had the "non-achto" version of armour obtained would have an increased chance of getting that Achto piece - this restriction has been removed and now the better drop rate just naturally applies.
