I agree that it would be beneficial for the players to have a DM ruling on what can fit into a Quiver of Ehlonna. I would like input from the rest of the group before declaring anything. There seem to be a few larger issues involved that we should probably resolve as a group before I come to a concrete decision.
With Quivers of Ehlonna (QoE), Heward's Handy Haversacks (HHH), and to a lesser degree with Bags of Holding (BoH) and Portable Holes (PH), we should come to a simple majority opinion as to whether what you can stick inside such a device is limited by the mouth or opening of the device. ie: can a composite longbow (which is fairly wide) fit through the mouth of a QoE, HHH, BoH, or PH? Could an anvil fit through? Can anything fit through as long as it doesn't exceed the internal storage limits? For BoH, HHH, and PH, the internal extradimensional space and weight limits are already defined in the DMG.
For a QoE, however, the storage limit isn't defined by cubic feet or weight. The DMG's QoE space is detailed in terms of numbers of three separate storage areas that can hold objects the "general size and shape" of 1.) 60 arrows, 2.) 18 javelins, and 3.) 6 bows. Are we then to infer from this description of the QoE that you can't store anything else other than those types of objects in it? Could a composite longbow fit in the bow compartment? If we do agree that objects other than items the "general size and shape" of those three categories can be stored in the QoE, does it seem reasonable to limit the cubic footage and/or weight to the equivalent weight limits of 60 arrows/ 18 javelins/ 6 bows?
We can spend the weekend hashing this out. If no one replies by Monday, I'll announce something then.
Right now, I'll put it out there that my personal inclination with regard to the QoE is that one waterskin of water probably could be stretched to two days of travel. Not very realistic, I know, but I'm comfortable with that for the purposes of travel. Water, however, is heavy stuff. One full waterskin weighs 4 lbs. The QoE doesn't really seem to be fashioned to carry waterskins. Up until this discussion, I wouldn't have tried to stick anything other than arrows/javelins/bows/staffs/spears in a QoE, mostly because the QoE costs less and weighs less than a HHH, PH, or BoH. To use it other than as described seems, to my eye, to be using it a way that circumvents the need to fork out more cash or be more encumbered. It has been suggested that players have a near obligation to "creatively" use their gears in ways other than what's described in the core books. I agree with that. This game is all about creativity. What I kind of sniff here, though, isn't about being creative but seems to have more to do with someone feeling as though they
need to pay less money to be able to carry more. Apologies to the player in question--I'm not meaning to be rude or to call you out. I thought about this as I was falling asleep last night and decided at the end that I'd better speak my mind on this issue so that we can fix it and move on.
I will also say that faced with a month's journey, players should probably expect to be somewhat encumbered with gear at the start of the journey. As you eat through/drink through/use up your expendible stores, your load will probably lighten. If you feel you need a lot of gear to survive (and I'd be with you on that) but don't want to be more than light encumbered, you might consider using pack animals of one variety or another to carry the overage. We can get creative with what kind of pack animals are available for purchase...horses probably aren't the best option for Underdark travel. And
that's the kind of creativity that I enjoy.
Again, I mean no offense to anyone. I would however, like to get this one decided on before Monday. Since this matters more to individual players than it does to the DM, players should have input here. We don't need to call anyone out in particular, either. I'd like a concensus all around about how you all want to deal with these kinds of things. Thanks.
