Just an FYI on the synth level. I'm 99 Cloth, 53 Gold, and 60 Leather. I used +1 gear Weaver body, tanner hands, and gold shades. With no support I crit failed this synth but I got a .1 skill up on cloth in the process.
All Ebon gear can currently be made via standard synthesis (albeit high levels, requiring sub crafts and using ingredients from new NMs). However, it's not until synthesis is released that we will see what potential this gear actually has. Synergy will allow up to three evolith augments, as well as being able to change the colour of the gear, giving it a different name (Furia/Ebur Frock). This effectively gives you the ability of having three of the same item with different augments while retaining the ability to choose which one you use in a macro.
Each of the 3 colors have different types of evolith slots for different elements. The Furia (Red) is "Light" based, and the Ebon (Black) is "Dark" based.
There has to be something more to these... The stats are not good enough to justify the cost, and there looks to be no HQ. So either SE has once again screwed poor people over, or they have something up their sleves
