D&D Fifth Edition Gambling Option

Now, in real life I figure a dollar in my pocket is worth far more than it would ever be on the table of a casino. However, with a Diviner at my disposal, gambling in the D&D world becomes a source of income, rather than a  reckless act of chance. 

After all, wizard spells get expensive. Why not have the DM add a little income on the side to keep your spell book well stocked?

Anyways, I've devised a couple gambling options for players of D&D fifth edition. Feel free to leave a comment if you can think of a way to streamline the system, or add in a little mischief should things go wrong!

Luck based gambling – Dragon Dice. Play one-on-one or with multiple players. Adding multiple NPCs also involves so many rolls that even with a character's 'Lucky' feat or a Diviner's 'Portent' ability, there is still a significant financial risk, for some large rewards.

1. Each player adds X amount of money to the pot, in an amount which is matched or raised by the next player.
   1. Each player can make an intimidation/persuasion check to goad his opponent into adding more cash to the pot, by insulting his pride, lineage, manhood, etc.
   2. Don't roll too high though on intimidation or persuasion (nat 20)… or his buddies might decide to ambush you outside the casino! Or perhaps they will encourage a femme fatal to dose your drink and take your winnings for herself…
2. Once everyone has contributed to the pot, they all roll a D20 and add their WIS modifier.
   1. Nat 20 wins the pot. Nat 1 loses automatically.
3. Whoever has the highest result keeps the contents of the pot. Start the next round.
4. Repeat as long as other takers are willing to contribute their funds.

I will eventually add a system to limit the funds available at the local casino, based on the size of the town and the amount of trouble you can find should you win too much, too fast. Stay tuned for more!
