Skipping Grades in Crafting

While you may attempt to improve an item directly from commercial to paragon in 1 day, doing so makes the DC of the Crafting attempt significantly higher and thus results in a higher likelihood of failure. It also makes it more difficult to craft using fewer materials when you have a formula than if you attempt to Craft the item one grade at a time. When upgrading multiple grades at once, you can only apply a cost reduction based on the cost to get to the next lowest grade. For example, if Chk Chk wanted to improve his commercial painglaive into a tactical painglaive the DC would be 16 and it would cost 350 UPBs to complete in 1 day. If he uses a formula, he can spend one or more days crafting to reduce the UPB cost using the Craft activity, up to half (175 UPBs) as normal. Chk Chk could improve his commercial painglaive into an advanced painglaive in one day with a DC 19 Crafting check and 650 UPB, but he would still be limited to reducing the cost by 175 UPBs. At any time, Chk Chk can stop upgrading his weapon and use it at whatever grade he achieved in the Crafting process, keeping track of whatever UPBs he's invested up to that point for future Crafting attempts even if the weapon gets damaged during the interruption.
