There seems to be some inconsistency in the game about what Monk fist weapons are counted as with regards to definitions of Melee, Weapon, and Unarmed attacks.
My understanding is they do not count as weapon attacks, but they should count as melee attacks. So I am not sure what the designation "Unarmed" attacks is meant for, expect to be as an exception to general melee attacks.
However there are some items, like Horns of the Berserker, that specify Unarmed and Melee in the description.
What then is the difference between Unarmed and Melee? In this case. If isn't this a redundant description as melee includes unarmed?
