New Magical Items (or slightly used, I can bargin! Yeh. Take this nifty bag of....)

[kirinke]

Quiver of Ehlonna, greater (or the Portable Armory): Like it’s lesser cousin, this appears to be a typical arrow container capable of holding about 20 arrows. It has three distinct portions, each with a nondimensional space allowing it to store far more than would normally be possible. The first and smallest one can contain up to 500 arrow-like objects. The second, slightly longer compartment holds up to 100 javelin like objects. The third and longest compartment holds up to 10 bow or sword like objects. Some wags call this device the portable armory.
Moderate conjuration. CL 9th. Craft Wondrous Item. Leomund’s secret chest, Shrink item. Price: 10000 gp. WGT: 2 lbs.

SCROLL CASE OF HOLDING: This appears to be a typical container (bone, wood, ivory) for holding scrolls, maps and other scraps of paper. Yet, it has been spelled to contain a number of scrolls, ranging anywhere from 100 to 500 scroll-like objects.
Moderate Transmutation CL 3rd. Craft Wondrous Item. Shrink Item.
PRICE: 2000gp. WGT 1 lbs

POTION BAG OF HOLDING: This appears to be a typical bag for storing a limited number of bottles or vials. It has been spelled to contain a number of potions, ranging anywhere from 100 to 500 bottles, vials or other such objects.
Moderate Transmutation CL 3rd. Craft Wondrous Item. Shrink Item.
PRICE: 2000gp. WGT 1 lbs.

Quiver of Ehlonna, greater (or the Portable Armory):

I'd say too cheap, offhand, but then again I think a lot of the extradimensional storage items are too cheap. 50 swords in one pouch is an awful lot. While it's nicely limited by only working for certain types of items, it's still just a huge amount of storage for a very cheap price. I'd rather see something with less storage and some new feature, myself.

For example, you could make the Psionic versions:
Portable Armory, Mundane
This small bag appears to be a small Bag of Holding, in many ways. However, it does not actually store any items, and cannot function unless it is empty.
As a Move-Equivalent Action, the user can reach into the bag and pull out any single shield or weapon (10 projectiles count as a single weapon), or any miscellaneous item (from the PHB table 7-8) worth 100 gp or less. Spell components, treasures (gems or currency), or living creatures may not be drawn this way.
These items are non-magical, non-masterwork items; they are actual, unattended physical items pulled from somewhere else in the multiverse. However, they faintly hum while present. Once 4 hours have passed, or if the summoner loses contact with the item for more than a round, it returns to its point of origin. Projectiles disappear immediately after striking their targets.
Only one summoned item may exist at a time; calling a second item causes the previous one to return to its origin immediately.
Caster Level: 4th, Call Weaponry, Call Item, Call Armor, 10000 gp

(Call Item and Call Armor are from the Mind's Eye, 8/29/03, "Psionic Potpourri". Price should be a bit higher, but it's pretty limited since those powers depend heavily on caster level and I don't let Call Armor pull actual armors. It's the Swiss Army Knife; never be without a lantern, rope, etc. again)

Portable Armory, Magical
As the Mundane version, except:
> The weapons and shields carry a +1 Enhancement bonus.
> The items have no price limit. Masterwork items may be called.
> The items last for 10 hours.
> Three summoned items may exist at a time. Summoning a fourth causes the first to return, a fifth causes the second to return, and so on.
> The hum is not audible, although the item vibrates slightly.
Caster Level: 10th, 30000 gp

Then, if you wanted to make your Greater Quiver of Ehlonna, just have a standard Quiver of Ehlonna that also functions as the Mundane Portable Armory, able to create nonmagical arrows or weapons on the spot.

As for the Scroll Case and Potion Bag, it's a nice idea. While they still seem too cheap, unlike the Quiver you're filling them with expensive items that have very little weight normally.
