Magic Damage or Intelligence

[Eidolon]

let's see...

DArklight Grimoir, as an example : Darklight Grimoir!

And the Deus Ex Verbis grimoir...

That difference of weapon damage is kinda surprising, but I don't see one that matches his INT parameters. BUT! The second one DOES have 17 VIT, he might be a little mixed up and reading the wrong primary stats. Because the first one was 15/15 (VIT/INT), and the second is 17/20 (VIT/INT)

[[final edit for my post]]

As another poster poitned out, the one with higher Magic Damage in this case is better, whcih is... REALLY WEIRD, but I think it's because of the fact that the first one is an entry-level 50 ACN/SMN/SCH item, and thus was adjusted for the use by both, while the second one becomes specialized. Eventually, you get to a point where item level (outside of HQ's) is really the determinant of Weapon Damage.
