Welcome, Master Alchemist! (A Simple Guide to Haggling)

On the vibrant island of Rafta, crafting the perfect potion is just the first step on the road to riches. The real profits are made in the thrilling dance of the haggle! It’s where your sharp mind and clever card play turn a good sale into a legendary one. But every great haggler knows the power of the **Deal Sweetener**. Think of it as your secret weapon—a little extra something you add to the final price to make the customer feel like they're getting a special deal, all while you're actually increasing your profits. Knowing the perfect sweetener amount is an art, but it's also a science. Add too little, and you leave precious gold on the table. Add one gold piece too many, and the whole deal can fall apart! It's a high-stakes game of precision.

This calculator is designed to be your most trusted business partner, the one who whispers the perfect numbers in your ear. It takes away all the stressful mental math and lets you focus on what you do best: playing your cards and charming your customers. By using the game's own formula, it gives you the *exact* maximum value you can add as a sweetener for a flawless, "Perfect" sale every time. No more guesswork, no more missed opportunities. It's time to turn that little potion stand into a world-famous emporium, one perfect, sweetened deal at a time.

How to Craft the Perfect Deal

Getting your maximum profit is as easy as brewing a Health Potion:

1. Enter the Potion's Price: This is the starting price after you've played any "Opener" cards.
2. Add Your Interest: Some of your best cards add "Interest." Tally up the total percentage from all the Interest cards you played and put it here.
3. Input Your Card Bonus: Now, add up the main bonus percentage from all the other cards you played during the haggle. Use the "Quick Add" buttons for common values!
4. Check the Customer's Stress: Right before you close the deal, glance at the customer's stress meter. Enter that final percentage here.

As you type, the results will update instantly. The "Max Sweetener Value" is the number you want to add to your price. The calculator even shows you the "Final Sale Price" so you know exactly what your grand total will be!

Pro Tips from a Potion Tycoon

• Interest is Compounding Gold: Don't underestimate the power of Interest cards! They increase the price that your main card bonus and the sweetener are based on, leading to an explosion in profits. Play them early if you can.
• Stress is Your Ally: A customer with high stress is actually a good thing for your bottom line. The higher their final stress, the bigger your sweetener can be. A carefully placed high-stress card right at the end can be a huge moneymaker.
• Know Your Customer: Every hero has a different personality and patience level. Learn their reactions. Some, like Baptiste, can handle a lot of stress, making them perfect targets for a big sweetener. Others might be more timid.
