I yearn to bring with me:

 One Truth-Telling-Gnome, vanquishing all lies that attempt to attack me, just like the sword of truth. Additionally it speaks all languages to persuade a dragon for its treasure. 

A hat, carrying eternal light, to guide me through gloomy caves.

To fight of  creatures that manage to conceal themselves into the pitch black darkness.

This sword.

To slay all unwanted spirits that attempt to to brawl with me.

It annihilates rivals.

A drone, scouting for danger. Whizzing through trees as it scrutinizes for misbehavior..
