UI element for an active Endeavor
The Endeavor System is a limited-time challenge based reward system for endgame players in Star Trek Online. Every two to three days at 9AM Pacific Time, a new task is distributed server-wide and any in-progress/uncompleted tasks will expire. These challenges range from completing R&D tasks or missions, to dealing damage to enemies with a specific energy type. Upon completion, a small amount of Expertise and Skill Points are awarded along with an [Endeavor Prize Pack].

- Endeavor assignment is account wide, meaning multiple characters on the same account can contribute to its completion. Once the assignment is completed, reward will be automatically given to the character that finished the task.
