Pact of the Gem
Your patron gives you a priceless Tiny gemstone called a Vault Jewel. When you gain this feature, choose one of your limbs. This gemstone is embedded within that limb or replaces it if they are of similar size, such with the case if you place it in your eye socket. Your limb still works as normal despite the gemstone's position.
This gemstone contains an extradimensional space, allowing you to store your wealth within it (no action required). This gemstone can hold coins, bullions, gemstones, and other systems of currency, as well as costly material components. This currency must be of size Small or smaller, and you must be touching it in order to store it. Retrieving a total amount currency equal to 100gp, or one item above that cost, requires a bonus action.
Eldritch Interest
As a bonus action, you can transmute any currency within your Vault Jewel into another currency. As such, you could turn 100 silver coins into 10 gold coins or 1 agate, 10 peridots into 1 black pearl or 50 platinum coins, or 3 platinum coins into 300 silver coins.
Additionally, so long as you keep an amount of gp equal to your character level within your Vault Jewel, your patron adds one gp into your Vault Jewel whenever you finish a long rest.

Soul Gem

You can contain the souls of the recently departed into your Vault Jewel. When a creature dies within 60 feet of you, you can use your reaction to contain their soul within your Vault Jewel.

While a soul is within your gem, you can cast the Resurrection spell without expending a use of your Mystic Arcanum. You can also cast the spell if you do not have access to the creature's body. Doing so causes the spell to provide a new body for the creature.
Once you have resurrected a creature in this manner, you cannot use this eldritch invocation again until 7 days have passed.
