The Red Mage Lethargy Armor +3 "Set: Augments Composure" enfeebling magic duration bonus is not being applied to Dia, Diaga, Dia II or Dia III

Steps:
1. As a "Job Master" Lvl 99 Red Mage, travel to Yahse Hunting Grounds
2. Approach a nearby enemy
3. Use the Red Mage job ability "Composure"
4. With no armor equipped, cast Dia III on an enemy and measure the duration of the spell. Duration will be 200 seconds which is expected (180 seconds base duration +20 seconds from job points)
5. Equip the "Abnormal Dia Duration" armor set listed below
6. Cast Dia III on an enemy and measure the duration of the spell. The expected duration is 300 seconds with all five pieces of Lethargy Armor +3 equipped (200x1.5=300), but the actual duration will only be 200 seconds indicating the "Set: Augments Composure" bonus is not being applied correctly.

"Abnormal Dia Duration" armor set
Head: Lethargy Chappel +3
Body: Lethargy Sayon +3
Hands: Lethargy Gantherots +3
Legs: Lethargy Fuseau +3
Feet: Lethargy Houseaux +3
All other armor slots empty

Might be a balance decision, beacuse Dia's counterpart, bio, is dark magic and isn't affected by any of this either. Dia really should be divine, but technically it isn't. So it could be for parity with Bio but SE would have to comment on this I guess. Just theorizing on my part. The only way to really know is to post it here, so good on you.

"not being applied correctly" more accurately, not being applied at all.
