The MLM

TBD

(Inspired by idea from user WandOfExpandDong)

Product Kit

Starting at 1st level you gain a magical chest that acts as an extradimensional shop from which you can buy any item from the player's handbook (chapter 5) at twice its regular value. The chest acts as a unique version of [Leomund's Secret Chest] that never expires. Any item bought must be able to reasonably fit the dimension of the chest's width - but depth plays no part.

When you make a purchase (or sale), you deposit coins or valuables (gems, jewelry, etc) into the chest along with a note with what you require as an action. At the end of your next turn the items pop out in an empty space next to the chest. You can use this feature a number of times equal to your Charisma modifier (minimum once), and regain all uses after completing a Short Rest.

If you wish you can also sell items at three times their value to other characters (PCs or NPCs), and receive X% of the sale price as a commission where X is equal to ten times your proficiency bonus. To sell at such an extortionate price is difficult, and may require skill checks as determined by the DM and/or roleplay where possible. If you try to buy something for another character using your discount your patron will know, and cut you off from your class features for a number of days equal to the price of the sale.

This feature is an investment, and to gain it you signed a contract with your patron that is magically binding and unbreakable except perhaps by the Wish spell. The contract expects you to try to network, recruit and sell wherever possible - but more pressingly you have a debt of 500gp that must be payed out of your own profits within six months of acquiring this feature. Each month you delay this repayment adds a cumulative 100gp to the debt.

Expanded Spell List

Your upline lets you choose from an expanded list of spells when you learn a warlock spell. The Expanded Spells table shows the MLM spells that are added to the warlock spell list for you.

Upline & Downline

There are certain expectations within your organization, any member of your group you did not recruit yourself that has a higher character level (or CR) than you is higher ranked - and thus should be deferred to where ever possible. After all they must have worked super hard to be where they are!

Additionally at 1st level your upline expect you to start recruiting more members that will sell for the patron, these individuals will become your downline and you will gain a percentage of their profits.

You can have a number of other creatures equal to your proficiency bonus sign a contract that grants them their own version of the Product Kit feature. If they are an NPC you gain a number of silver pieces equal to their challenge rating every week, fortnight or month (this is best decided by the GM based on the pace of the campaign they are running). Once you fill your downline you cannot sign new members until others are removed for whatever reason (usually death).

If another player signs your contract they gain the Product Kit feature, and any sale they make you gain 20% of the total sale price.

The contract itself is binding and effectively automatous, meaning you need not follow up with your downline. Any profits are automatically found within you Product Kit.

Specialty Product

As you rank up in your patrons eyes you gain access to some of your the specialty items your company offers.

Starting at 6th level you can buy the following items by spending 1000gp through your Product Kit. 

• A bracelet made with precious gemstones ([Stone of Good Luck]) ~ sold as something that brings wealth and prosperity
• High quality clothes with unique and interesting patterns ([Cloak of Protection]) ~ sold as unique fashion that fits all sizes
• A collapsible flask ([Decanter of Endless Water]) ~ sold as a source of endless filtered natural stream water
• A cross stitched satchel ([Bag of Holding]) ~ each sold as one of a kind handmade bags
• Matching lockets of gold or silver ([Sending Stones]) ~ sold as his and hers type lockets 
• Tinted glasses ([Eyes of Minute Seeing]) ~ sold as glasses to combat eyestrain

You can have number of these items equal to your proficiency bonus at any one time, unfortunately your patron has a no refunds policy ("sorry hun!") and if you want to change items you have to return the unneeded ones through your Product Kit. Additionally you can't sell these items until you reach 14th level, but when the option is available you must sell them for 1500gp and follow the rest of the rules and guidelines from your Product Kit.

You and your GM can always work out other items that may be available, but generally they shouldn't be rarer than uncommon, and they shouldn't be things like +1 weapons or armour.

Company Spells

Starting at 10th level you can now buy potions and scrolls from your Product Kit, the prices of these items are as followed;

Potion, common 160gp (240gp when sold to others)
Potion, uncommon 600gp (900gp when sold to others)
Spell scroll, 1st-level 200gp (300gp when sold to others)
Spell scroll, 2nd-level 1100gp (1650gp when sold to others)

Any sales still follows the same rules as your Product Kit feature.

Fake It Till You Make It

Starting at 14th level you can use your product kit and cast a spells you normally could not.

As an action you may name a spell and reach into your product kit, casting it following the normal rules for the chosen spell - except you must double any required material components and pay an additional number of gold pieces equal to 100 x the spell's level.

You can use this action a number of times equal to your Charisma modifier, and regain all uses after completing a Long Rest.
