Increased Weapon Size Damages

[DM Buckeye]

Greetings..

If a weapon (GreatSword) has 2D6 for base damage and has the weapon has a bonus of Impact on it then Enlarge Person is cast on the person, what would the new damage be?

The errata FAQ states these are 2 different weapon size change types so they would stack.

Is it 2d6 to 3D6 for Impact then what when enlarged?

Thanks.

You take the chart in the FAQ and go up 4 steps (2 steps for each size increase), so 4d6.
