I would take a,

An encrypted ball , that is full with magical treasure, so I can get my money/belongings.

An official guide to monster hunting (just in case I get into trouble with a monster) so I can always be one step ahead.

My full potential dragon (that has a rude attitude) so I have protection.

A magical diary (that put all your thoughts and felling in it) so I can remember the adventure I had.

My encrypted tablet , that can entertain me when I’m bored, so I can take videos or pictures of my adventure.

My trusty wand (over 1000 years old) so I can punish those who dare to defy me .

A life time supply of food (something I can’t live without) so I can eat when I’m hungry.
