Can a skill carry over through salvaging?
Solution 1:
You cannot salvage any parts that enhance an attribute. You can only salvage parts that you see add elemental damage, damage, hp, mana, etc,...
Edit:
I just tested a theory. you can make a lot of money off of items that have +1 to an attribute tree. An item without it sold for about 14k while an item with it sold for about 54k. So, consider selling it later instead of salvaging it.
