Quality
|
Quality is a stat: An item's quality is how well-made it is.
Many crafted items and some structures have a stat called quality. This stat influences various attributes of the item, according to the tables below.

At higher quality levels
If a crafted or built item is at least excellent, a piece of random artwork will be engraved on it. This is only meant to add depth and has no further effect.
If a crafted or built item is masterwork, there will be a simple text notification at the top of the screen saying that a colonist has crafted a masterwork item.
However, if the item is legendary, there will be a proper notification letter.
As of Beta 19/1.0 masterwork and legendary items never generate on enemies, traders or in bases. They are only available through player creation or as quest rewards, though masterwork items can spawn in ancient shrines.
How quality is determined
When an item requiring a quality is crafted or built, that is, when crafting finishes, the quality is randomly determined using a standard distribution. Expected values by skill level of the crafter are given in the table below.
- The column "Avg. Result" shows the mean quality for each skill level, where awful = 0, poor = 1, normal = 2, etc. The mean quality becomes "normal" at skill level 6, however already at skill level 4 the character will have a 50% chance to craft something that is at least of "normal" quality (median quality).
- The "Avg. Value" column gives the average market value multiplier for that skill level. At skill level 6 you can expect a character to stop wasting material value from crafting.
As quality is rolled once an object is finished, it is possible to have builders work on something until it is almost done, then have the master finish it to get a better quality on the item. This tactic is particularly useful for high work buildings such as royal beds, as it both alleviates the high workload on the good builder and allows their "apprentice" to grind experience. Note however, that as crafted items and art assign "authors" to the unfinished work, this strategy cannot be used for those items.

Inspired creativity and Legendary items
In core RimWorld, Legendary items can only be made if the crafter currently has the mental inspiration Inspired Creativity. Note however, that with the advent of the Ideology DLC, the addition of the Production specialists adds the chance to get to get "legendary" items without an inspiration. See below for details.
When a pawn is granted the Inspired Creativity inspiration, the next item, structure or piece of art with a quality level will automatically be two levels higher – thus, if "excellent" or "masterwork" is rolled, a legendary item is produced instead. Even the most capable crafters have only a 60% chance per inspiration to produce a legendary item.
Inspired creativity makes it impossible to craft an item of poor or awful quality; at least normal will be rolled, even at 0 skill level.
Since the inspiration takes effect only when the item is finished, it is useful to raise the skill level of the inspired person as high as possible before actually producing an item; for example you can train crafting on several items that do not have the quality stat (eg. components or bionic body parts) before using up the inspiration.
It is also possible to keep an unfinished item in stock, and wait for an inspiration to occur before actually finishing it; this will still reap the full effect, without requiring you to dedicate a lot of work during the 8-day time window of the inspiration. This strategy is particularly useful for work intensive projects that are always in demand (eg. marine armor or a grand sculpture)
Pawns with the Tortured artist trait can be purposefully given mental breaks by giving them poor treatment such as awful bedrooms or nutrient paste to intentionally trigger Inspired Creativity inspirations. Similarly, if the Royalty DLC is enabled, the use of the Word of Inspiration psycast can be used to generate more creativity inspirations, though other inspirations may be granted instead. Otherwise, keeping pawns in high moods is the only way to increase inspiration frequency.

Production specialists and Legendary items
 | This article relates to content added by Ideology (DLC). Please note that it will not be present without the DLC enabled. |
With the advent of the Ideology DLC, the addition of the Production specialists adds the chance to get to get "legendary" items without an inspiration. When created by a production specialist, any item, structure or piece of art with a quality level will automatically be one levels higher – thus, if "masterwork" is rolled, a legendary item is produced instead.
Being a production specialist makes it impossible to craft an item of awful quality; at least poor will be rolled, even at 0 skill level.
This bonus stacks with Inspired Creativity inspirations, resulting in works three levels higher i.e. if good is rolled, a legendary item is produced instead.
