Okay, here are some basic descriptions of all the upgrades.
Dungeon Master's Guide:
-Bottle of Air (7 250 gp)
[spoiler]This item appears to be a normal glass bottle with a cork. When taken to any airless environment it retains air within it at all times, continually renewing its contents. This means that a character can draw air out of the bottle to breathe. The bottle can even be shared by multiple characters who pass it around. Breathing out of the bottle is a standard action, but a character so doing can then act for as long as she can hold her breath. [/spoiler]
-Decanter of Endless Water (9 000 gp)
[spoiler]If the stopper is removed from this ordinary-looking flask and a command word spoken, an amount of fresh or salt water pours out. Separate command words determine the type as well as the volume and velocity.
"Stream" pours out 1 gallon per round.
"Fountain" produces a 5-foot-long stream at 5 gallons per round.
"Geyser" produces a 20-foot-long, 1-foot-wide stream at 30 gallons per round.
The geyser effect causes considerable back pressure, requiring the holder to make a DC 12 Strength check to avoid being knocked down. The force of the geyser deals 1d4 points of damage but can only affect one target per round. The command word must be spoken to stop it.[/spoiler]
