* Increases an equipped weapon's ATK/MATK by given rate.
* bWeaponMatkRate does not work in pre-renewal as there is no MATK for weapons in pre-renewal.
* Renamed 'bonus2 bWeaponAtkRate' to 'bonus2 bWeaponDamageRate'.
- Seems to be unused in the current item database.
- Damage fits the bonus name better as it increased the final damage, not the weapon's attack specifically.
