I was a Lvl 30-40 death student and you should take out the minions because they are easy. 1.Chester Droors heals early and has full health. This means you take out the minions early so that they can't heal him. 2.If you have blades and traps similar to a death student.Use it on minions and kill them
Use a minion to fight him.. When I did it I didn't have any traps so don't worry.
All you need to do really is get a friend to help you.I am also a wizard, and I have already defeated him. You dont really need traps if you have a friend to help you.I had a friend with me and no traps so thats all you need to do.
