If you add ingredients when crafting, it gives more xp. I thought I had to farm all these ingredients... Until I found this: It's Necromacy merchant in Thanos bazaar. It sells bone meal and rotten flesh, so you don't need to worry for ingredients in woodworking, weaponsmithing, armoring and tailoring! And there's potato merchant in Brimminglar, so no worry for cooking ingredients too. Now you have to only get ingredient for scribing, jeweling and alchemism. How come did no one tell me this before?
