As a reward for the 2020 invasion event, it gives a bow with a BANE option.
This is an image of OSI.

The bane option on a weapon cannot be crafted.
The bane option in Bow, which appeared in the 2020 invasion, should not affect the total property weight and the count of properties.

ItemProperty solves the total weight properties, but it is hard to know where to control the count of properties.
Should this attribute be adjusted in each weapon file?
