training points can be hoarded or saved up until YOU know what your wizard needs to learn...but if it involves attacks not from your own school might end up needing to farm for or buy a mastery amulet.. consider all your options before spending any, because unless you luck out via good timing and have membership at same time, training point buyback isn't free :/ a great guide that can help newer wizards is swordroll's 10 things you wish you knew when starting wizard101, hope this helps some :3 best of luck stormy jen silver
