weapon.attribute_name["attribute] doesn't give you the calculated attributes including all children like it does when applied to a being/player

[Sihoiba]

My understanding is being.attributes.field gets you the value of field as set on the being, and being.attributes["field"] gives you the calculated value as changed by perks,

This doesn't work on weapons both versions of the check only you get the value on the weapon, you have to manually check for every child that alters the value to get the total.
