Aid Grimmle... first step:

[Canine]

Ok anyone that smiths knows about the horrid fail rate at the worst times so im wondering:

If you fail this step:

Breastplate decorating: (Forge, Trivial >250)
(Coated) Breastplate
Black Diamond of Nightmares
Black Diamond of Nightmares

What does it return?

[Gapper807]

I didn't fail this step but if it's anything like the Jewelcraft step then the answer is...

Nothing! Absolutely nothing!

[Kronepsis]

All of the parts that don't use the signet return nothing, AFAIK.

[Canine]

Ok but you will always get your signet back, correct?

(FYI i did compleate that first step YAY me!)

[Taraddar]

I didn't fail the final combine but I did fail the first step, the cleaning of the bp and you didn't get the bp back there so I would expect the same here.
