Weapons on hand, do they also use inventory slots?
If a character is holding their bow in their hands, does it still use 2 inventory slots?

They still take up inventory slots. "Inventory slot" are just a measurement of what a character can carry with them, whether it is in their hands, backpack or on their body. If you want a system that uses separate slots for body, backpack and hands you should take a look at Mausritter by Isaac Williams, Errant by Ava Islam, or The Electrum Archive by me :)
