This skill can be performed with any of
the following weapons: ... and any object made entirely of open cell
foam that is not a thrown weapon.
I don't understand this. Is it basically saying "Don't try and use the weapon for both throwing and waylay"? Because I don't see any way that somebody can objectively say one open cell object is for waylay and another is for thrown weapon.
A big reason I ask is because if you go to http://www.medievalcollectibles.com/c-528-larp-throwing-weapons.aspx there is a rolling pin, a pan, and a mug in "throwing weapons." These seem like items that are perfect for a sap... but they're throwing weapons.
