{{Stat|description = An item's quality is how well-made it is.}}

Many [[Skills#Crafting|crafted]] items and some [[Skills#Construction|structures]] have a stat called ''quality''.  This stat influences various attributes of the item, according to the tables below.

== Effects of quality ==
===General===
Effects that are common to several, or all, types of object.

:{{note||Meditation Bonus|A}} Only applies to [[Sculptures]]. Note that this is NOT a factor, but instead a flat bonus.

=== 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. <br>
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 shrine|ancient shrine]]s.

== 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 bed]]s, 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 [[Ideoligion#Production specialist|Production specialists]] adds the chance to get to get "legendary" items without an inspiration. See [[#Production specialists and Legendary items|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. [[component]]s 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 [[Trait#Tortured artist|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 [[Psycasts#Word of inspiration|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===
{{Ideology|No category}}
With the advent of the [[Ideology DLC]], the addition of the [[Ideoligion#Production specialist|Production specialists]] adds the chance to get to get "legendary" items without an inspiration. Any item crafted by a production specialist will be 1 quality level higher than 

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.
