An edge that halves the weight of worn armour and shield

[Gumbytie]

So I am working on file for Beasts and Barbarians and stumped myself building this Edge: Hoplite Training.

In a nutshell:

When calculating encumbrance, he considers only half of the weight of the armor and shield he wears.

Any ideas if this is possible? Can we do a search and look for worn armor and shield and modify the weight value?

Okay, I have had a chance to test this code to make sure that it works before sharing it.

Phase: Pre-Traits
Priority: 5000

var weight as number
weight = 0

~ Get total weight from equipped armor
foreach pick in hero from Armor where "Equipped.Equipped"
    weight += eachpick.field[gearWeight].value
nexteach

~ Get total weight from equipped shields
foreach pick in hero from Shield where "Equipped.Equipped"
    weight += eachpick.field[gearWeight].value
nexteach

~ Apply the half of the total as a reduction to total encumbrance.
weight = round(weight / 2,0,-1)
perform #resspent[resEncumb,-,weight,"Reduced Weight"]

I know that the "Reduced Weight" is redundant, but I like to use it as it is a comment in itself and makes the code more readable.
