On Aptitude: If you want to clear up Lightning Maces and change it to what I suspect was intended, change the wording to
"If the wielder of an Aptitude weapon has any feats or abilities that grant a special benefit with a particular type of weapon, and the type of weapon to gain the benefit can be chosen (and must be chosen) upon gaining the feat or ability, then the Aptitude weapon gains the same benefit just as if it were a weapon of the same kind as the wielder's choice for the feat or ability. Furthermore, if the Aptitude weapon actually is of the same type as the wielder's choice for the feat or ability, attacks with the weapon gain a +1 bonus on attack and damage rolls.
Thus, the wielder of an Aptitude spiked chain who had Exotic Weapon Proficiency (bastard sword) would not take a nonproficiency penalty for wielding the chain, but would not gain the benefits of a feat such as Superior Unarmed Strike that grants a benefit to a specific weapon."
Or something like that - the examples are a bit odd, I admit, but hopefully get the point across without using any material other than ToB and Core (you could change the EWP example if you wanted).
