Players will often find Elite Enemies in the open world while exploring, or in Domains and the Spiral Abyss. These enemies are stronger than Common Enemies and can drop some of the same Common Ascension Materials that common enemies drop, as well as Artifacts and ascension materials exclusive to elite enemies. Some Elite Enemies will serve as a mini-boss in certain quests.
Note: There are a limited number of spawns per day, which will reset daily according to whatever the Daily Reset Time is for your server/region.
There is a daily limit of killed Elite enemies yielding normal drops, the value is 400. Killing any more than that will drop nothing. This is not restricted by the world level, meaning that changing world level (for example in co-op) will not increase this limit.
