Rare Enemies have a 10% base chance of appearing in most Quests. This chance is doubled to 20% in Co-op mode.
All rare enemies have a chance of dropping Four-Leaf Clover which are needed to increase Dragon Bond level at the Dragon's Roost. Currently it is believed to not be possible to obtain rare enemy loot when using a Skip Ticket, however it appears yet has not been confirmed that rare enemies can spawn with a reduced rate compared to running the Quest normally when using a Skip Ticket.
The element and difficulty of a Quest determine the variation in rare enemy spawn. Expert and Master difficulty spawns are dependent on the player's might value. Limited-time event quests such as Raids or Facility Events may have unique spawn variation while Story quest variation is still unknown.
