Sung Lee offers a focused boss encounter with a build-specific drop pool, making it a concrete option when you want to pursue its rewards rather than rotate through unrelated bosses.

WHERE & HOW TO FARM
Where to farm
Eternal Battlefield → Sung Lee encounter.
Use the Eternal Battlefield route when Sung Lee’s encounter and rewards fit your current build goal. Entry costs 50 Battle Fragments, so treat each attempt as a limited, paid run: check your fragment supply, prepare to handle the boss, and collect the encounter rewards before deciding whether to buy another entry with your time. The drop pool is focused, but a specific item is not guaranteed.
Unlock access to the Eternal Battlefield and Sung Lee encounter.
Have 50 Battle Fragments available for an entry.
Bring a build that can sustain a boss fight and recover safely.
Set your loot filter to show Sung Lee rewards relevant to your build.
Check your Battle Fragment count before committing to the encounter.
Confirm that Sung Lee is available through your current Eternal Battlefield access.
Set your loot filter to retain useful equipment and rewards for your build.
Enter the encounter, accounting for the 50-fragment entry cost.
Defeat Sung Lee using your normal boss positioning and damage pattern.
Collect and inspect the rewards before leaving the encounter.
Compare the result with your build goal and fragment supply before choosing another entry.
Farming tips
Treat this as a focused drop-pool farm; confirm that its reward pool matches the item or upgrade you want.
Include deaths, recovery, and the fragment cost when judging whether repeated attempts are worthwhile.
Repeat, collect and use
Sung Lee can be attempted again when you have access and another 50 Battle Fragments. Rewards vary by attempt, so repeated entries do not guarantee a particular item.
Common mistakes
Entering without enough fragments: check the 50-fragment cost before committing to the run.
Assuming a focused pool guarantees a desired drop: evaluate each attempt by the rewards actually collected.
Continuing after the encounter no longer serves your build: save fragments for a better-matched target.
When to stop or switch
Stop when you obtain the upgrade you came for, run short on fragments, or find that the rewards no longer advance your build. Resume when Sung Lee’s pool again matches a specific goal.
