WHERE & HOW TO FARM
Where to farm
Adventure > Joint Operation > Spacetime Training Ground, when the current schedule lists it.
Spacetime Training Ground is one of the rotating Joint Operation areas. Its eight difficulty tiers have level gates, and the activity awards random equipment and matrices after the team defeats its bosses. The schedule reference places Training Ground II on Friday and Sunday, but the in-game schedule is the final check for the active variant and reward options.
Meet the chosen difficulty’s displayed level requirement; the listed tiers run from Level 20 through Level 70.
Have the current Vitality cost shown by the activity.
Form or join a team for the boss encounters.
Open the current Joint Operation schedule and check whether Spacetime Training Ground is available.
Confirm the variant and reward pool in the activity panel.
Choose the highest listed difficulty your character meets and your group can clear steadily.
Enter with the team and defeat each boss in sequence.
Review the reward chest preview before spending Vitality.
Open the chest and collect the displayed reward result.
If the pool still matches your goal, repeat while you have Vitality and the activity remains scheduled.
Farming tips
Training Ground II is listed for Friday and Sunday in the schedule reference; confirm the current Global schedule before planning around those days.
The guide lists eight gates, from Level 20 to Level 70; use the in-game gate if the schedule has changed.
Repeat, collect and use
Repeatable during its scheduled availability, with each reward attempt costing the Vitality shown in-game. Drops are random, so repeats do not guarantee a particular armor piece or matrix.
Common mistakes
Trying to enter a tier above your level: compare the gate before queueing.
Assuming the older weekly schedule is permanent: check the live activity schedule.
Opening chests without a useful pool: inspect rewards first and save Vitality if the target is absent.
When to stop or switch
Stop when you have the desired gear improvement or the instance leaves the schedule; switch to another current Vitality activity if its rewards fit better.
