I seem to be unable to glamour Mogwand onto Thyrus.

- Glamour Conditions
Glamours may be cast with any items that meet the following conditions:

The base and projected items are of the same type (hands, feet, etc.).
Both are weapons, check.

The equipment level of the projected item is equal to or lower than the base item.
Thyrus Zenith is i90, Mogwand is i75, check.

The base item and projected item are equippable by the same class or job.
Both WHM, check.

The base item and projected item are equippable by the same gender or race.
Not applicable but check anyways.

For gear occupying more than one gear slot, one the following conditions must be met in addition to the above:

The base item and projected item occupy the same number of gear slots.
All of the projected item's gear slots fall within the base item's gear slots.

Example:
Able to cast glamours
Casting the glamour of a robe on a hooded cowl, as the body and head slot of the hooded cowl include the body slot of the robe.
Mogwand occupies main hand slot, same as Thyrus, only difference being that I won't be able to equip a shield. Check.

Thyrus is repaired by GSM, so I made a level 4 GSM prism (i61~i80) and level 5 GSM prism (i80+) just in case, and Mogwand is repaired by ALC so I made a level 4 ALC prism and level 5 ALC prism. That's every possible combination, yet when I try to glamour, Alkalurops is the only thing that shows up as a valid option.
