I was creating a Paladin recently and came across a conundrum...save for a Daily power, he has no ranged abilities, meaning I can't engage a creature I cannot reach by the end of my turn.

So my question is...is it possible to PICK UP a javelin, throwing hammer/axe/dagger, etc. after it has been used? And do I need to "buy" multiple javelins, etc. to use more than one per encounter?
