Your family's bloodline stopped running crimson long ago: now, gold and silver flow through your veins, thanks to your family's long-time connection to some wealthy, corrupt power source. Perhaps your descended  from a cruel, malevolent investor, or some greedy, litigating demon.

Perhaps you are a descendant of The Don or a close personal friend of Queen Killary. Perhaps your parents earned their money legitimately but you yourself had the misfortune of coming down with the terrible sickness; Affluenza. Regardless, your great wealth and your magical ability are now inextricably linked, for better or for worse.

Tax Evasion

Starting at 1st level, anytime you would be made to unwillingly spend or lose money, you may simply substitute someone else's. Amounts of less than 10 gold magically disappear from coin pouches within 120ft of you (divided as evenly as possible?). Amounts of 10 gold or above require you to spend 1 sorcery point per 50 gold (minimum 1 point). If this loss would bring the victims below the point of having no money, the remaining total is deducted from your funds.

Trust Fund

Also at 1st level, you gain a bonus to your spell save DC and spell attack rolls based on the highest type of currency you are carrying (+3 for a Buck (100 gold), +2 for a Platinum, +1 for Gold). 

Eldritch Bribe

At 6th level, your wealth, status, and privilege have deeply intermingled themselves with your magical ancestry. You may spend money to gain a bonus on your next roll. For every 1 sorcery point spent and 10 gold spent, add 1d4 to your next ability check, attack roll, or saving throw.

Nesting-Doll Yachts

At 14th level, your obscene inherited wealth has granted you access to a plethora of modes of transportation. No matter where you are, you may spend 5 sorcery points to have a generic vehicle, appropriately sized for your party, which exists somewhere in the world (at the DM's discretion) delivered to you in an " as-new" quality within one hour.

A Mysterious, Unfortunate, Unavoidable Accident

At 18th level you may spend X sorcery points to have a single creature anywhere on your plane of existence who does not have this class feature and is not currently in possession of a Murkan Buck(100 gold) (or its equivalent value in gold, silver, or copper) take X*10 irreducible damage of a type of your choice.
