Help me please, I'm just returning after a long lay-off and when I tried to use this schematic I get that I don't have the appropriate crew skill. I have over 500 on Armstech and the schematic said I only need Armstech 280.

So is it me or the game that is wrong ... Did they change these to a different crew skill or are they just no longer recognized ?

Please help,

Thanks!

Indeed. Trainer schematics for Critical Augments are all for Synthweaving, as are the yellow Umbara ones.

And of course two other points:

* Critical Augment 15 is antique junk. (The current CA 17 requires Synthweaving 290...)(1)

* No augment below 228-purple is worth even bothering with.

(1) Comparison, although it's for "Redoubt", which is Defense/Power, rather than Critical, because that's the only Augment schematic my oldest Synthweaver has in her Archive.

* Archive: Redoubt 22 = Green, rating 106, requires level 44, requires Synthweaving 390, +13 Defense, +8 Power

* New: Redoubt 21 = Blue, rating 112, requires level 42, requires Synthweaving 340, +14 Defense, +10 Power

So, OP, ignore it. It's junk and you can't use it.
