Master of Coins

Money is power. Everyone knows this. For a Warlock whose Patron is a Master of Coins, this can translate into magical powers and abilities. Their Patron may be a demigod of wealth, a mystic bank, or even a potent noble whose wealth and power have allowed them to literally "purchase" a Warlock or their contract from another source. A Warlock who serves the Master of Coins seeks to climb the heights of wealth and power, and many achieve this... for a price.

Expanded Spell List

The Master of Coins lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Spend Money

At 1st level, once per Long Rest, a Warlock servant of the Master of Coins can purchase an additional spell slot from their Patron as a bonus action. This extra spell slot costs the Warlock 100 gp times the Warlock’s Spell Level and cannot be used on Mystic Arcanum slots.  If the Warlock does not have sufficient funds, their Patron may select an item to take in exchange instead. If the Warlock does not have sufficient funds and nothing worth trading, this ability cannot be used.

Make Money

At 6th level, while taking a Short Rest, a Warlock servant of the Master of Coins can sacrifice an item to their Patron to immediately obtain its value in gold pieces. If the item is not magical, use its value per the book. Magic items, if sacrificed, grant money as follows: common magic items earn the character 100 gp, uncommon 400 gp, rare 4,000 gp, and very rare items earn the character 40,000 gp. Legendary items and artifacts cannot be sacrificed using this ability. (although the Master of Coins may grant other boons for items of such intense power)

Always Be Selling

At 10th level, as a Reaction to another character starting their turn, you may sell that character some of your Patron’s power. If the character willingly sacrifices 50 gp, they may then gain the ability to cast any 1 level spell, using your Spell Attack and Saving Throw DC and your Spellcasting Ability score. The money is instantly transferred to your Patron and the character may use the spell gained any time between now and their next Long Rest. You may provide this benefit a number of times equal to your Proficiency Bonus until the end of your next Long Rest.

Master of the House

At 14th level, you gain the ability to cast Mordenkainen’s Private Sanctum as the spell, without any material components, once per day, without requiring a spell slot. While inside the extradimensional space created by this ability, you have Advantage on all Charisma-based checks and automatically succeed at all Saving Throws.

Once you use this ability, you cannot use it again until you finish a Long Rest.
