I was just wondering,
all or most of the subguilds which include crafting (for instance, stonecrafter or tailor or jeweler) get the skill value.
Does this skill just count for the item of their subguild (for instance, a tailor can only 'value' clothes) or does it count for all items?
I'm pretty sure it counts for everything.
It counts for everything.
You're free to roleplay being far more familiar with the values of your chosen trade of course.
All items.
Be aware that value fails in a variety of interesting ways.
