Okay, on Direwolf node 1 you cannot light fires. To progress through witchery, you need to light a fire under a witch's cauldron, and you cannot do that. What do I do? I really like witchery and I want to get farther in.
Alternatively, you could place lava near it, with logs around the lava so it will spread to netherack or something like that. There is also a Thaumcraft wand focus that lights fires, but I am not sure if that will work or not.
