Quality Level Items

[LennyLen]

Another question, do the items you have affect items found or are able to be bought from Griswald/Wirt? For instance, let's say I have a "Bow of the Stars", would that make me more likely to get/be offered a "Jade bow of the stars"? Or is it all random?

For shopping in town, the only thing that has an effect on item generation is the level of the character, so no, it doesn't matter what items you already have.

If you want a more in-depth explanation of how item generation works, you might want to look at chapters 3.8 and 3.9 of Jarulf's Guide.
