If I take
1. Catch off guard,
2. throw anything,
3. Improvised Weapon Proficiency,
4. Splintering weapon,
1) Can I use magical, enhanced arrows as *improvised* daggers, and on a successful hit add the 1d4 bleed damage, as well as get the special effects associated with the arrow? I imagine that the arrows break anyway after a melee hit, anyway. And ditto for using arrows as improvised thrown weapons.
2) Would I forgo the +1 to attack from the masterwork quality of the arrows, since "masterwork" improves an item's effectiveness at it's intended task, and I'm using the arrows in a manner different from what it was specialized for? All other bonuses from the arrow remains though, right?
3) Can I draw arrows as a free action, even though I may use them as improvised melee weapons (or thrown weapons)?
