Request for additional moddable damage type property

Description

I would like to request a new property be added to damage types. The goal is to simulate occasional "critical hits" which skip armor entirely. There is already a "Penetration Percent" property which allows damage to skip armor/shields. I would simply like to associate a random chance with the Penetration so that it doesn't happen all the time.

For example, one method would be to add a "Penetration Chance" property. If specified then the Penetration Percent is only applied some of the time.

Armor Type 1 Name := Normal
Armor Type 1 Penetration Percent := 100
Armor Type 1 Penetration Chance := 5
Armor Type 1 Damage Percent := 100

In the above example, I have added the "Penetration Chance" property. The net effect of all the above is that there's a 5% chance that the damage will penetrate 100%. The other 95% of the time, penetration is ignored.
