Wilki EA - UO Developer posted this last night in the Test Imbuing thread on stratics:
We've added an exception so that museum rewards are not imbuable. The way they were created makes it difficult for the imbuing system to handle them.
Also, the line "This only applies to new items created after this change." in the patch notes is supposed to be a sub-bullet for the line above it. To clarify, it only applies to items made from or enhanced with special materials, not artifacts or other items.
After further thought, a double weight penalty to properties on items that normally wouldn't have them is too harsh. However, it is still something we're looking at.
That said, another issue that we're looking at, and has been commented on in this thread, are properties that exceed the normal intensity cap, such as SSI on the general's bows. What are your thoughts on some penalty to weight for properties that exceed the normal intensity cap? It could either be a straight percentage to the entire amount, or perhaps just to the amount over the cap.
As always, we're looking forward to your feedback.
------------------------------------------
Then posted this:
Because of the limited number of item slots that some properties can be applied to normally, there is a "soft cap" for some properties as far as realistic use is concerned.
Lets say you found 3 items that had SSI in slots where it naturally doesn't belong. Of those 3 items, only one of them was commonly used, as the other two were lesser artifacts that sacrificed too much for players to consider using them for the extra SSI.
The same goes for items that allow properties to exceed the normal caps, as that acts in much the same fashion as having it on an item slot where it normally doesn't belong, except in that case, it doesn't even take up an extra property slot.
However, if you allow them to be imbued without any additional penalties, suddenly they're now being used in combinations that weren't practical or competitive before.
That's what I'm worried about.
--------------------------------------------
It looked like in his first comment that he said items crafter after would be the only ones that could be imbued.
It doesn't really matter in the end. You can just pop out some runic bows after the patch until you get the 40ssi anyway and take it from there if need be.
