Engraved Goatskin Grimoire: Why No Mind?

[ChibiChan_Hyperion]

You have a point, I was not factoring in that the non aetherial item is a level 30 grimoir.

that said, it is possible that an aetherial version would drop with MND since its base attributes + randomised additional attributes up to 5 slots.

Aetherial items will only randomize the secondaries, and never add new additional primary stats different than what the base item has (Piety is not considered a primary stat, while Elemental Resistance is). In this example, every Aetherial Engraved Goatskin Grimoire will have Vitality and Intelligence since these are the primary stats that exist on the base item. The rest of the stats can only be randomized secondaries. There can never exist an Aetherial Engraved Goatskin Grimoire with Mind on it because the base item does not contain this primary stat.

Essentially, this is the reason I bring it up. If it was given to the base item, then the Aetherial item would also have it.
