After remembering about that head because of MNK Boost TP build. I decided to do a power search on AH all the old Hecatomb NQ/+1 also say Slow +X% instead of "Slow"+X%
https://www.ffxiah.com/search/item?&description=Slow%20%2B#adv
There is a ton of stuff that says Haste + vs Haste+.
IIRC in the last few months SE had mentioned this also in patch notes. iirc? Looking now.
Edit: NVM that's different as per the July update notes.
"Certain augments with “Haste+%” and “Slow+%” do not display the percentage sign.
* This is a display error only. The effects of these augments are functioning properly."
Edit 2: Now that I had more time the Haste + error is only 5 items.
Geo. Galero +1 (27705) Says Haste +6% instead of Haste+6%
Rune. Bandeau +1 (27706) Says Haste +8% instead of Haste+8%
Spae. Coat +1 (27831) Says Haste +3% instead of Haste+3%
Pill. Armlets +1 (27969) Says Haste +5% instead of Haste+5%
Dynasty Mitts (28034) Says Haste +3% instead of Haste+3%
Edit 3: Heres the Hecatomb gear with the Slow + issue
Hecatomb Cap (13927) 9%
Hecatomb Cap +1 (13928) 11%
Hecatomb Mittens (14076) 5%
Hecatomb Mittens +1 (14077) 7%
Hecatomb Leggings (14180) 4%
Hecatomb Leggings +1 (14181) 6%
Hecatomb Subligar (14308) 12%
Hecatomb Subligar +1 (14309) 14%
Hecatomb Harness (14378) 13%
Hecatomb Harness +1 (14379) 15%
Edit 4:
I think you should add a note especially if this list is to get handed to SE at some point.
"Laksamana's Tricorne +2 (ID: 23056) / Laksamana's Tricorne +3 (ID: 23391)
Inconsistency - Other COR Artifact Head Equipment is called "Hat" not "Tricorne"
Tricorne is a newer term they started using and imo Hat is the wrong text and they all should be a Tricorne since they are Tricornes.
I think when they first added AF they hadn't decided to use this term and when they did the first 109/119 (+1) they just used the term on the old AF instead of being smart and renaming to Tricorne like they did with +2/+3 to fit in with the rest of of the Relic/Emp gear/style.
Edit 5: This might of been an error when they first added EMP gear and they kept up with it. The spellings are interchangeable but I feel like it was just someone else translating later on why we got the different spellings.
WHM Bodies: Briault vs Briauld
All AF uses Briault
All Relic uses Briault
Blessed Briault / Blessed Briault + 1
I made a mistake below:
All EMP uses Briauld.
Orison Bliaud (12030)
Orison Bliaud +1 (11186)
Orison Bliaud +2 (11086)
Ebers Bliaud (26902)
Ebers Bliaud +1 (26903)
Edit 6: (June 10th, 2019) When they added "Zantetsuken X" they changed the JP description to say "時々物理防御力を無効化" on Coruscanti to match Zantetsuken X but left the English text alone instead of changing it to the new description.
Coruscanti (19144) Says: Occasionally ignores physical defense
Zantetsuken X (21664) Says: Occasionally nullifies enemies' defense
Edit 7: There may be an issue with DRK Relic hands. The old NQ/+1/+2 say "Gauntlets" but the new iLVL NQ/+1/+2/+3 say "Finger Gauntlets". The AF nor EMP change from "Gauntlets". Getting a bit late so I didn't look at JP text. Just stuff I remember dealing with in templates of BGWiki when making them.
"Finger Gauntlets" are normally reserved for DRG gear.
