The Dark Ring is one of those items that separates players who are actively progressing from those stuck spinning their wheels. You need it for Ascension 3 and the Solo Hunter sword, two of the most impactful mid-game unlocks in Sailor Piece. The catch: it drops from a single boss at a rate of 7-10%, and you need up to 8 total across both uses. That means a lot of trips to Sailor Island.
Where does the Dark Ring drop in Sailor Piece?
The Dark Ring drops exclusively from the Jinwoo boss (also called the Solo Hunter), who spawns inside the central shrine building on Sailor Island. Getting there is straightforward: open any teleporter on the map, select Sailor Island from the menu, and hit teleport.
Here's where new players often get tripped up. Jinwoo shares his spawn point with Alucard (the Vampire King), and the two alternate. If Alucard is standing there when you arrive, you have to kill him first before Jinwoo appears. According to Beebom's guide, Jinwoo respawns every 5 minutes after Alucard is defeated.
Server hopping is an option if you want to skip the Alucard kill, but it can eat up more time than it saves. Killing Alucard also drops useful loot you may need later, so grinding through both bosses is the more efficient play.

What is the Dark Ring drop rate from Jinwoo?
The sources give slightly different numbers here. PCGamesN reports a 7-9% drop rate, Beebom states 10%, and Sportskeeda cites a base rate of 7%. The variation likely reflects the impact of Luck bonuses. At base stats with no luck boosts, expect around 7%. With accessories, Titles, or developer-granted boosts active, that number edges toward 10%.
At 7%, you will need to kill Jinwoo roughly 14 times on average to get a single Dark Ring. For the full 8 rings required across both uses (5 for Ascension 3 and 3 for the Solo Hunter sword), you are looking at potentially 80 to 100+ kills in the worst case. Stack every Luck bonus you have before farming.

warning
Do not skip the Luck optimization step. The difference between 7% and 10% might sound small, but across 100 boss kills it translates to roughly 3 extra Dark Rings.
How to farm Dark Rings quickly
Jinwoo is described by Beebom as one of the easier bosses in Sailor Piece, with 6 million HP. You do not need top-tier gear to clear him, but your kill speed directly affects how many runs you can complete per hour.
Optimize your damage output
- Check the Sailor Piece tier list and equip the strongest sword or melee style available to you at your current level.
- Use races and clans that provide extra HP and damage bonuses. According to Beebom, these can give meaningful stat advantages that speed up clears.
- Redeem any active Sailor Piece codes for rerolls, which you can put toward better race or clan stats.
Boost your Luck
- Equip accessories that increase Luck before each kill attempt.
- Apply any active Titles that carry Luck bonuses.
- Watch for developer-granted Luck boosts during events, which Sportskeeda notes can raise your drop odds above the base rate.
Manage the spawn cycle
- Stay in the same server and kill both Alucard and Jinwoo back to back on each cycle.
- If you have a group, coordinate kills so nobody is waiting idle during the respawn timer.
- Trading with other players is a valid shortcut. The trade menu is accessible from the left-side screen panel. Cross-check what you are receiving before confirming any deal.
What do you use Dark Rings for in Sailor Piece?
There are exactly two uses for the Dark Ring, according to all three sources.
Ascension 3 requirements
Speaking to the Ascension NPC on the edge of the Jinwoo and Alucard boss arena triggers the Ascension process. Ascension 3 requires the following, per Sportskeeda:
Completing Ascension 3 rewards you with 10% Gems, 10% Money, 2% Cooldown Reduction, and 5% Luck, all of which compound your progression going forward.
Solo Hunter sword requirements
The Solo Hunter sword (Jinwoo sword) is obtained from the Jinwoo Trainer NPC located at the rightmost edge of Sailor Island. You need to complete the Trainer questline first, then hand over the following items per Sportskeeda and Beebom:
Both Abyss Edge and Shadow Heart also drop from the Jinwoo boss, so you will likely accumulate them during your Dark Ring grind without needing separate farming sessions.
info
The Ascension NPC and the Jinwoo Trainer NPC are both on Sailor Island, so you can knock out both interactions in the same session once you have enough Dark Rings.
Planning your Dark Ring grind
The math is worth doing before you start. You need 5 Dark Rings for Ascension 3 and 3 for the Solo Hunter sword, totaling 8. At a 7% base drop rate with a 5-minute respawn cycle, Beebom estimates you can realistically collect a few rings per hour of consistent farming. Luck boosts push that number up noticeably.
The Ascension 3 requirements beyond the rings, specifically the level 6000 threshold, the 500 NPC kills, and the 10 Shadow Dungeon clears, mean you will likely hit those milestones naturally by the time you have farmed enough rings. The Dark Ring count is the actual bottleneck.
