Appearing to be an ordinary corked glass bottle, this item contains a limitless supply of fresh air. You must uncork the bottle with an Interact action before you can activate it.

Effect You draw a breath of air from the bottle. This allows you to breathe even in an airless or toxic environment. Air doesn't escape the mouth of the bottle, so leaving the open bottle in an airless environment doesn't change the environment.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
AirEffects with the air trait either manipulate or conjure air. Those that manipulate air have no effect in a vacuum or an area without air. Creatures with this trait consist primarily of air or have a magical connection to that element.
ConjurationEffects and magic items with this trait are associated with the conjuration school of magic, typically involving summoning, creation, teleportation, or moving things from place to place.
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
