Seeten said:I think Skip, and the others, make the same mistake I made originally, which is not carefully reading the table, and then making assumptions.
Or possibly they noted the difference between the table and the text of the ability and realized the table was in error. Perhaps yours is the mistake.

Seriously, does anyone really think that Sunder does not belong in the same category as a normal melee attack, a disarm, or a trip?
If one can use a weapon to disarm a foe's weapon with an AoO, doesn't it also make sense that one could use a weapon to attempt to sunder the weapon with an AoO? Is there a valid logical or game balance reason for this not to be the case? I think one would really have to stretch to come up with a reason that it does not make sense or that it imbalances the game.
