Darks Are Getting Fast Cast/absorb Adj??!!

Forgot about those, but they're only 1% FC.

Is my set. AF2+2 works for Darkmagic? What about stun?

AF2+2 text states Black Magic, so at the very least I'd assume it works for dark magic and may work for elemental and black-aligned enfeebles as well (break, bind, gravity, sleep, etc). Depends on whether they actually meant all black magic or if it was a typo for dark magic. Hard to tell since it doesn't affect recast. Might be able to rig something up with waits to check though.

Actually, if I remember right -casting time is multiplicative with fast cast... so you'd really have 1-0.78*0.92=28.24% cast time reduction, or 29.16% with Nebula +1 hands.

Doubt it applies to anything but dark.

JP:
暗黒魔法の詠唱時間短縮-8%
Google trans shows this as:
-8% casting time reduction of dark magic

French:
Temps de lancement des sorts de magie sombre-8%
Google translates to:
Launch time spells dark magic-8%

German:
Sprechzeit von Dunkelmagie-8%
Google translates to:
Talk time of dark magic-8%

What you quote as german translation is actually french, and the french one is german!

Copy paste fail ^^; Fixed.

Isn't ACP body cast time only and not recast?

ACP Bodies have Fastcast +5 as an augment choice, which affects both. It's what I use on my blu for FC.

Figured as much, would've been pretty unusual if it affected all black magic.

Does it work with Stun? Can anyone test before I go and buy a ton of forgottens.

I don't have any testing, but stun is dark magic and while there is some question about if it might affect other magic types due to poor wording on the English description, dark magic should be affected so go for it.
