Considering the pamor related powers, I've heard form some people that a specific pamor doesn't allways indicate only one "power".
For example a was wutah keris is best known for his "good luck" quallities to the owner but it could be for "pengayoman" (protection and saccor) also.
There are some cases that I have encounter about keris that were made for more than one "purpose" for their owners (and I am not speaking for keris with two pamors etc, in this case), I know of an old maduranese blade
(very strong and for fighting) made for a warrior with the purpose of "coming back safe from the battle" and it has pamor was wutah. This keris is not for general protection or for protecting the family of the warrior, but it was strictly for the warrior in battle. Maduranese people were mostly poor those days, so a was wutah pamor was ideal for someone to have a good luck in general. But the empu could "issue" another power in the blade not so obvious for other people than the owner himself.
Have you ever heard something similar?
