Traits, introduced in Plunder, are effects that modify default behavior of a Kingdom pile they are attached to.
Traits are not Kingdom cards.
There are 15 Traits, any number of which may be used in a game of Dominion, though Donald X recommends not using more than two total Landmarks, Events, Projects, Ways and Traits. When choosing a random Kingdom, the Traits may be shuffled into the randomizer deck; any Traits that are dealt once 10 Kingdom cards have also been dealt will be included in the game.
At the start of a game with a Trait, you randomly pick which eligibile pile (only Action and Treasure piles) is modified, and the Trait card can slide under the pile, leaving the text showing and the name on the sides. Hence the layout.

 Official Rules
Plunder has Traits, which are a new kind of landscape card that affects a single Action or Treasure pile. At the start of a game with a Trait, choose a random Action or Treasure Kingdom card pile to put the Trait on; then during that game, cards from that pile are affected as indicated on the Trait.
- Traits are not Kingdom cards, and are never bought or gained.
- Traits only go on Kingdom cards, not on e.g. Silver or the Ruins pile (from Dark Ages).
- Don't put two Traits on the same pile.
- Traits refer to the pile using the name of the Trait; for example Pious refers to "Pious cards." That just means, any card from that pile.
- A Trait on a split pile (from Empires and Allies) affects all of those different cards.
- Traits continue to affect the cards from a pile even after the pile is empty.
- Events and Traits can be shuffled into the randomizer deck (despite having a different back). They are not part of the 10 Kingdom cards used in a game; when an Event or Trait is turned over, put it on the table but keep turning over cards until you get 10 Kingdom cards. For normal play we recommend using at most 2 such cards; with other expansions that includes Events, Traits, Landmarks, Projects, and Ways. Skip any further landscape cards turned over. Also skip Events and Traits when using a randomizer card to determine whether or not to use Platinum/Colony (from Prosperity), or Shelters (from Dark Ages) in a game, or to determine the bane for Young Witch (from Cornucopia). Another approach some people may prefer is to shuffle Events and Traits (and Landmarks, Projects, and Ways) separately into their own deck, and always play with one or two of them.
- In games using a Trait, pick a random Treasure or Action from the dealt-out Kingdom cards and put the Trait under it, so the text is showing; do not put two Traits on the same pile.
