Cross out the dagger for me,im not a good person,i would use the cube and use it to get the rock while im at it,then id wish for the ability to find any living thing and then id teleport to the dragon via seeking it out with the rock,I'd then use the wish to make me completely righteous,then i'd use the rock to get the ability to find any object on earth,then i'd locate the dagger and teleport to it via the cube and then i would just make a pocket dimension to live eternally with no worries,i would give my loved ones the ability to contact me any time and be absolutely immortal too so i would handle their problems for them.
