Unable to use Solus Ipse Grand Visage as Monk Acolyte Chayula

Hello

I am unable to use Solus Ipse Grand Visage as a Acolyte of Chayula. I have all the stat and level requirements fulfilled. When I wear the helmet, it says, you cannot use this item, its stats wil be ignored.

Why is this?

same issue, trying to figure it out. stats do meet the criteria. im on witchhunter

I cant use it as well im a Titan

Found out it takes more stats than it shows because it increases its own requirements and of other items by 25%. Pretty simple anwser realy.
