Question About Improv

[PepsiWhirda]

Hey, say I want to throw my melee weapon in a fight, to take out someone who's escaping or something.  Do I need ranged proficiency to do that, or is it assumed I'm proficient enough with the weapon martially to accomplish this?

Edit: And a question about extraction.  If Whirda chose to (for in character reasons not yet written, such as a sudden need for as much OM as possible to settle a vendetta or something), can she extract it from, say, fresh corpses of enemies?  Like if she killed goblins would they be worth OM, provided she spent the time required?
