Initially I picked salvaging and talismans for crafting skills.  Salvaging was especially frustrating.  I often got a message saying an item was not salvageable or that I wasn’t skilled enough to salvage an item.  But I never found information in an item’s description to indicate if it was salvageable or what the minimum skill level requirement is to salvage it.

So around level 18, I switched to cultivation and alchemy.  Not great, but better.  Cultivation is especially interesting since I can plant a seed and close the window.
