Hey, I figured out how to make a weapon's
weight from Heavy to Light...
Go into game.bin / OBJECTS / OBJECT_IRON_LONGSWORD / CWeaponDef and you will see that the Iron Longsword has a CLASS of 1.
Now go into game.bin / OBJECTS / OBJECT_IRON_BROADSWORD / CWeaponDef and you will see that the Iron Greatsword has a CLASS of 2.
Since we know that the Iron Longsword has a Light weight and the Iron Greatsword has a Heavy weight... Simply change the Iron Greatsword's Class to 1 and it's weight is now Light.
YAY! Now my Bereaver is a Light weight!
Enjoy
