Introduction

The Gilded Rose is a small inn with a prime location in a prominent city run by a friendly innkeeper named Allison. It buys and sells only the finest goods. Unfortunately, the goods are constantly degrading in quality as they approach their sell by date. We have a system in place that updates our inventory for us. It was developed by a no-nonsense type named Leeroy, who has moved on to new adventures. Your task is to add a new feature to our system so we can sell a new category of items.

First, an introduction to our system:

Current System Behavior

• All items have a SellIn value which denotes the number of days we have to sell the item
• All items have a Quality value which denotes how valuable the item is
• At the end of each day our system lowers both values for every item
• Once the sell by date has passed, Quality degrades twice as fast
• The Quality of an item is never negative
• “Aged Brie” actually increases in Quality the older it gets
• The Quality of an item is never more than 50
• “Sulfuras”, being a legendary item, never has to be sold or decreases in Quality
• “Backstage passes”, like aged brie, increases in Quality as it’s SellIn value approaches; Quality increases by 2 when there are 10 days or less and by 3 when there are 5 days or less but Quality drops to 0 after the concert

New Requirements

“Conjured” items degrade in Quality twice as fast as normal items
