As I understand it from reading the chapter about crafting staffs (p. 552 Core) you are able to put any spells you want in a staff, the cost just goes up.
But at the end of the section on Staffs, there is a paragraph about there being additional cost for specific staffs.

My quistion is this then, are you able to craft a staff with spells of your choosing or are you limited to the specific ones listed in the magic items chapter?

I was going over the rules for combat maneuvers, thinking about diffrent concepts for a master of combat maneuvers-type character. I was thinking of either a monk or fighter, or a combo of the two.
And then it got me thinking of fighting style of Jackie Chan, always grabbing whatever is handy, the opponents weapons, tables, boxes etc
And I thought it would be cool if i could recreate that with the monk and some feats in Pathfinder

"Improvised Monk weapon"
Prerequisite: Flurry of Blows class feature, Catch Off-Guard feat
Benefit: Any Improvised weapon you use, counts as a monk weapon.

"Monk Disarm"
Prerequisite: Improved Disarm, Improvised Monk Weapon
Benefit: You are considered proficient in any weapon you are holding as a result of a succesful disarm attempt until you are no longer holding that particular weapon. In addition any such weapon is also considered a monk weapon for you

I have thought of making "Monk Disarm" a 1 round effect to simulate the fast nature of Jackies fighting style, and to keep it from being overpowered. Any thoughts or suggestions, like better names for example :-D
