Weapon Adaptation [MA]

[acrosome]

I have a question on how techniques work with weapon adaptation. Take Glaive Fighting (MA187) as an example, because the idea of combining Staff skill with a duelling bill is awesome.

Let's say I want to be frugal with points, and I want to favor the Staff skill awesomeness, so I only put one point into Polearm but buff Staff really high. Then I take Weapon Adaptation (Polearm to Staff).

But I also really like Hook and Sweep attacks. If I have Hook (Polearm) because it's included in the Glaive Fighting style, but I'm mostly using Staff skill to fight with the bill per Weapon Adaptation, do I base by Hook attack off Polearm skill or off of Staff skill? I assume Polearm. (I know, I know, I could just buy Hook (Staff). But that seems less true to the style, or something...)

I could Style Adaptation (Polearm and Quarterstaff), but this still doesn't get me Hook (Staff). Or does Weapon Adaptation (Polearm to Staff) allow me to buy Hook (Staff)? Or does Style Adaptation (Polearm and Quarterstaff) allow it?

AND THEN, if I do have Hook (Staff), can I use it to hook with the bill???
