A Field Boss (also unofficially called World Boss[1]) is a powerful enemy that is found in the open world of Lost Ark, rather than confined to a dungeon or main quest. Unlike dungeons, any number of players can work together to defeat a field boss.

Each field boss appears in a specific location, and counts towards Adventurer's Tome progress.

All field bosses have a health multiplier of ×23, which means that their health must be reduced to zero 23 times before they are defeated.

Field bosses have a relatively long respawn time depending on their health:

  • Below 10 million HP: Respawns 30 minutes after being killed.
  • 10 to 20 million HP: Respawns 2 hours after being killed.
  • Over 20 million HP: The field boss is a Raid enemy, respawning on a set schedule (hourly 11 AM to 5 AM on Tuesdays, Fridays, and Sundays). Players can see the field boss's next respawn time by either selecting its raid icon on the map or by checking the game's calendar in the top left corner.

High-level field bosses also have a Recommended Item Level. If the player's item level is below this value, they have a reduced chance of hitting the field boss and might not earn any rewards for participating in the fight.

Some bosses drop rewards that are necessary to complete a zone's cooking part of an adventure tome.

Rewards[ | ]

Field Boss rewards can be claimed once per day per roster.
