a way to do this... once you have learnt the stronger version of the spell *you would need to give the book to an npc* they would give you the stronger spell (they would add you to a namelist or something).. when you log out and back in it would use the same npc thing *sorry not used 1.9 files alot lolz* that it does to tell what lvl you are or say your online.. and if you are on the namelist it could delete the weaker spell and give you the stronger spell without you even knowing
