The wielder of a two-handed weapon on a sunder attempt gets a +4 bonus on this roll, and the wielder of a light weapon takes a -4 penalty. If the combatants are of different sizes, the larger combatant gets a bonus on the attack roll of +4 per difference in size category.
If a medium sized character wielding a two-handed weapon was attempting to sunder a large creature's light weapon, what would the creature size and weapon size modifiers be?
Does the large creature get a penalty for the light weapon? Or does that only affect the "sunder attempt" and not the opposed attack roll?
Does it matter that the large creature's light weapon would be a one-handed weapon for a medium sized creature?
