when crafting items does my characters level matter? or any particular stat? And if I combine items unsuccessfully do I assume that I can never combine them or that maybe I will be able to once I have found a recipe? For example, I tried combining Drudanae and an empty potion bottle but was surprised to get nothing from it. That seemed weird, so I checked the wiki and sure enough it's listed as producing a potion. Any help would be appreciated. Thanks
