But can you wear more than one quiver at a time? And what happens if you run out of arrows, do you:
1. drop the empty quiver, pull out the new one from your backpack/bag of holding, equip the new quiver (3 move equivalent actions)
2. drop the empty quiver, equip the backup one that was hanging from your waist (2 move equivalent actions)
3. sling the backup quiver over your other shoulder (1 move equivalent action)
4. just start drawing arrows from your backup quiver
I wouldn't mind seeing better rules for this sort of thing. I played a ranger once, and during combat the rogue ran out of arrows so I had to give him some of mine. We had some trouble adjudicating just how many actions are needed, and how many arrows can I give him.
