Shaintar: Legends Arise Edge problem #1

[Gumbytie]

Okay, so I have a copy of the Beta book and found some cool Edges similar to some house rules I was thinking of.

First one:
WEAPON FINESSE
Requirements: Novice, Agility d8+
The Hero has learned how to use grace and dexterity in place of raw power to get more out of their weapons. As such, they may use their Agility to determine their damage with melee weapons, rather than their Strength.
For example, a Hero with an Agility of d10 and a Strength of d6 would normally be limited to 2d6 total damage with a chuktar (the goblinesh blocking blade), and they would not get the benefit of the +1 Parry it confers, due to the fact that they don’t have the minimum Strength necessary to properly wield the weapon. If they have Weapon Finesse, however, the damage goes to d6+d10, and they would gain the +1 Parry.

So while cool, it hurts my head thinking about coding that

Somehow you need a script that replaces the portion in <component id=WeaponBase, the script that checks to see the Minimum strength requirement is met.

validif (#trait[attrStr] >= minstr

is switched to:

validif (#trait[attrAgi] >= minstr

If someone now has this Edge. Any ideas to start?
