Golden Blood

Whether born in the slums or a noble house hold one thing is certain you were born to be rich. You've always been able to sniff out the coins people have dropped, and your a master at getting a deal. You don't know exactly when these talents became mystic in nature, but it was likely at the same time that your skin started to have flecks of gold in it. 

Living Vault

As a Golden One at 1st lvl, your affinity with money is such that you can absorb it within you in order to keep it safe from greedy hands. So long as at least 100 golds worth of currency and gems is stored and have no armour your AC is 14+ your Dex modifier, the more gold you absorb the more gold your skin becomes.

You've also spent your life bartering for your sales and purchases, if you can get a lower price you will, and if there's a higher price to be reached nothing can stop you. Your Charisma bonus is doubled for the purpose of bartering in any deal where you can gain or lose money.

Liquidate Assets

Once your magic truly starts to appear at 6th lvl, you can skip the bartering process altogether and simply turn an item you own into gold for 1 sorcery point. 

Note own for this ability means either purchased, found, gifted or stolen successfully. A successful theft means that the owner is either dead, unaware, or unable to do anything.

False Life

At 6th level you've learnt a strange art to create life by spending gold you can create. It's always been argued what a life is worth now you know the precise amount.

Spend 150 gold and 5 sorcery points to make a false life (use the soldier statblock, including the chainmail). These beings will have no will of their own for the first week, and will only gain sentience after a month. Their life span at start is 6 months, but can be increased for 10 gold per month, their hit points are 16+ you sorcerer level ×2. For an additional 25 gold and 1 sorcery point at creation they can spawn with either a longsword or the firbolt cantrip, you can have both for 50 gold and 2 sorcery points.

Their appearance will be that of a bald male changeling unless otherwise specified. 

Perfect Copy

At lvl 14, spend 10000 gold pieces and a quarter of your max sorcery points to summon any creature with a CR equal to 2 thirds your player level (round down), then roll a D4 to determine how much you control it. 1-uncontrolled could do anything 2-disinclined to attack you and your allies 3-won't attack you or your allies 4-perfectly under you control will do anything requested of it. This ability will quarter you sorcery points so long as the Perfect Copy remains, a Perfect Copy cannot be dispelled and must be killed. You may only have one Perfect Copy at a time.

Heart of Gold

At 18th level you have well and truly become one with gold as it flows through your veins and guards you from damage. 

Spend your highest level spell slot and all current sorcery points to gain temporary hit points equal the amount of gold you spend divided by 10.
