I am looking at the schematic for the Custom-built Lightsabers, both the Double and Single, and they list the Force Power as +51 yet looking at my Schematic in my Crafting window I can craft them at +58.

 

Does that stat change after you learn them or level up?

Not entirely sure, but there seems to be a random aspect or two, the first time I crafted a Lightsaber it came with an Augment Slot, and while most were at same level, one had better hilt mod.

I just found it odd that it list one thing on the Schematic you use to learn it and another thing when looking at what I can actually craft.

It must just be a mistake in the listing. I just crafted one and it made a +51 Force Power and not a +58 like it list.

I notice the damage is listed a little more as well.

I think they should fix that so it list what you actually make. People are going to think they can make one with slightly better stats than they really can.
