Enhancement is an effect granted by using Nourishment utility.png utility consumables and are often used in tandem with Nourishments obtained from Nourishment food.png food consumables. While food consumables include nearly every food-like consumable in the game, utility consumables include all other sources.

You can have a single enhancement active, unless noted in their description. The effect is replaced if you consume another item providing an enhancement, even if it is the same enhancement effect. Enhancement effects and nourishment effects are separate and can always stack with each other.

For example, you can stack the attribute boosts from an Artisan Maintenance Oil (a Nourishment utility.png utility) and an Omnomberry Pie (a Nourishment food.png food), but eating another Artisan Maintenance Oil will reapply the effect and restart the time instead adding time to its duration, and using an Artisan Tuning Crystal (another Nourishment utility.png utility) after the oil will result in the crystal's boost replacing the oil's.

When an Enhancement effect expires, the character will gain the Diminished.png Diminished effect for 5 minutes. The only purpose of the Diminished effect is to act as a reminder that an Enhancement has ended and has no other effects on the character.

  • Like booster effects, enhancement buffs last until they expire or are replaced — they persist through defeat and zoning.
  • The duration of Enhancements counts down only while the character is logged on. If you switch characters, the timer stops.
  • The duration of Enhancements can be extended with Utility Primer.pngUtility Primer or Flask of Utility Primer.pngFlask of Utility Primer.


  • Originally, utility buffs ended after zoning, defeat, or logout. They were changed in an update to behave more like food.
  • Originally, Enhancements were also called Nourishments, but they were renamed to make it more clear they are different effects.
