I would take a invisibility potion so i could sneak around the deadly dragon.

I would take a metallic dagger and a fire proof chestplate so i can protect myself from the dragons firey bloody breath

I would take a pair of feathry boots so if i jump of a building or a mountin so i dont take any fall damage.

I would bring a red cape so it can protects me from the enemys arrows and the dragons breath but also used for when i jump off a mountin the cape can save me.
