You draw upon the hidden energies of the Astral Plane to create a personal extradimensional space known as the Vault of the Celestials with a certain hand-sign. This space serves as a vault where you can store and retrieve objects with ease, summoning them through shimmering white portals that you control at will.
Vault of the Celestials
When you cast Vault of the Celestials, you open a portal to a personal, extradimensional space within the Astral Plane. This space can store up to 10,000 pounds of anything. Items placed within the Vault are kept in stasis, meaning they do not age, decay, or suffer from the passage of time, though there is no Air inside . The space is highly organized, allowing you to mentally catalog and retrieve any item stored within it.
Extradimensional Nature
The Astral Vault is a unique pocket dimension, and only you can access it. The vault is immune to detection and cannot be interacted with by others unless they possess extraordinary means, such as specific planar magic or artifacts that allow entry into sealed dimensions.
Portals
As a bonus action, you can summon a portal that connects to your Astral Vault. The portal appears within 50 feet of you and can be up to 10 feet in diameter. This portal is visible to you and anyone around. It shimmers with a faint, ethereal, white light. While open, the portal allows you to interact with the contents of the Vault. While the portal is active, you can use your action to retrieve or store up to 3 objects from the vault at a time. The total weight of objects you can interact with in a single action cannot exceed 200 pounds. You may also dismiss the portal as a free action, instantly closing the connection to the vault.
Weapon of the Vault
Any weapons stored within the Astral Vault are instantly accessible. When you summon the portal, you can call forth a weapon from the vault as a free action, instantly equipping it.
Astral Shield
As a reaction to being targeted by an attack, you can summon a portion of the stored objects to form a temporary barrier around yourself. This grants you a +5 bonus to AC against that attack. The barrier can be composed of various objects from the vault, such as shields, armor, or even mundane items. Any Items used in the process will get damaged, possibly destroyed.
Quick Change
If you're in a situation that requires immediate preparation, such as transitioning from social attire to battle gear, you can do so in a single action
