I don't think this is the case. In native the extra_penetration flag appears to just use the extra_penetration soak and reduction values for calculating armour damage reduction, but in WSE2 when I use extra_penetration it seems to be multiplying the damage value by the soak factor +1. Not sure if it's also affecting the armour calculation or not.
I see, thanks. Does extra_penetration work the same way with WSE as it does in native? As in the damage soak is essentially just overwritten with the extra_penetration soak values?
You've convinced me to watch the LOTR trilogy again, congrats.
