I was for the realism option of recovering arrows,

But, gotta say, A one of cost makes me *And my Coins* fairly happy.
Personally I'd at least like to see Varients of arrows, like poison stats and silence (Kabura arows? <.<)
That is, an extra stat for a "Gil Sink" as you put it.

sum up since I kinda rambled on into obscurity.

Consumable arrows: Would like to see some with extra bonuses like poison/Silence
Non-Consumable: Just generally like this idea.
