I've leveled my blacksmithing up to level 10 and am now interested to see what it means to mastercraft an item. From several other places I've read, this simply indicates that I should now be able to craft epic level (purple) equipment and that the bonuses granted passively per item type should reflect that.
However, in practice, this has not been the case. Even using the highest level ingredients (e.g. Prismere Chakram Discs, Flawless secondary/optional components, and gems), the items I create still come out as green or blue, with the appropriate stats to boot.
I have noticed that adding gems to a recipe feels "odd", in that not nearly all of the gems I have in my inventory are available for crafting. Understandably so for Epic gems which are restricted to chest slot / robes, but definitely not 100% sure on how this functions.
Am I missing an essential aspect of this, or is there something more subtle that I'm just not grasping (e.g. underlying math, component types, etc.)?
