Bastion of the Infinite Vault

Every Bastion of the Infinite Vault is mystically bound to a hidden extradimensional armory known only as the Infinite Vault. Through disciplined training and specially gifted access—whether by runes on your body, arcane technology, or other means—you can open momentary rifts that retrieve exactly the equipment needed for the battle at hand.

"You briefly open a stable portal to an infinite extradimensional repository, drawing forth a single object before the rift seals." or "You borrow treasures from possible futures, where you already own them." or "You retrieve items stored within an ancient planar vault."

Planar Armory

Beginning when you choose this archetype at 3rd level,

For 1 minute, as a bonus action, you can summon one uncommon magic item from lists like the Dungeon Master’s Guide.

This item must not be consumable or require spellcasting in its use. It must be a weapon, shield, armor, adventuring gear, or a wondrous item. The item can cast spells, but must not require the user to be a spellcaster.

While this item is summoned, you are considered attuned to it.

Once you have summoned an item, you cannot summon it again until your next long rest. You can only summon one item at a time. Summoning a new item will cause the old one to automatically return to the dimensional vault. You cannot sell an item summoned in this way, attempting to do so will make the item disappear.

Holding on to this summoned item for the duration of the minute requires concentration, as if concentrating on a spell.

You can use this feature a number of times equal to your proficiency bonus.

You will gain access to more powerful, rare items as you level in this class.

You attune to items you find quicker, taking 10 minutes instead of an hour.

Greater Requisition

Starting at 7th level, You can now summon rare items from lists like the Dungeon Master’s Guide.

Additionally, you have been requisitioned your own private vault, which functions like a bag of holding. You can retrieve items stowed in this vault with a bonus action. (Add yourself.)

You cannot store items summoned by your Planar Armory feature in this separate space. Stowing items summoned by your Planar Armory feature will merely return them to the infinite Vault, unable to be summoned again until your next long rest.

Dimensional Adept

At 10th level, In addition to one summoned item of rare or lower, you can summon a second item only if it is a weapon. This second item is included in the same concentration check and duration as the first item. Meaning, when you lose access to the first summoned item, the second will go along with it.

Vault Master

Starting at 15th level,

You can use your Planar Armory feature to summon very rare items.You can attune to items you find in an instant.

As part of an attack action, you can summon an item in the same attack as long as it is a weapon. You can chain extra attacks with different weapon summons, spending a charge each time as usual. Once the second weapon is summoned, any third weapon will immediately replace the first, and so on.

Legendary Requistion

At 18th level, you can attempt to use your Planar Armory feature to summon a legendary item.

Legendary items demand a worthy bearer. At the end of each of your turns while wielding any legendary item summoned in this way, make a DC 15 Constitution saving throw. On a failure, the portal collapses and the item immediately returns to the Vault.
