Before setting out on an adventure, you can customize what you bring with you. After a bit, you eventually have multiple forms of weaponry (bone spear, iron sword, etc). Each has it's own weight so carrying multiples could end up being an issue.
Is there any benefit from taking one of each (1 sword, 1 spear) or multiples of the same (2 spears)?
Ranged weapons have obvious benefits since there are different types of ammunition, but for melee, it seems only the best weapon is used.
