Lantern, Candels, other light sources for asthetics. for practical use, have a chance at lighting fuel sources (oil,..fur..people)
Bones of all types to be Grinded down into Bonemold armor Enchanted with the Soul of my First Dragon kill as a testament that I am almighty!
tin/Iron/metal objects aformentioned throwable, but also able to smelt them for future weapons/ Armor/ arrows.
anything that can be griped and has lenght and a good width functions as a poor mans Sword

Throwing bottles and foodstuffs to start a good ol Nordic Barfight.
