[dev] Is Stat Effect on Quality working?

[tymora]

That's what Unerring Hand, Piece by Piece, By the Book, Grand Design or Tricks of the Trade are for, so you don't have to worry about breaking if your synth is at least 20/30% to completion.

I don't use them in favor of Greater Calling. Rapid x 3 with it gives me close to 30% if it fails and 60% if successful.
That said, anything can happen in the greater cause of higher quality!
