Key takeaways

  • Fishing the wrong water. The Vale’s main lake has a similar look but a completely separate spawn table. The Celestial Pond is the smaller, darker pool past the second waterfall.
  • Casting in daylight. No amount of bait overrides the time lock.
  • Using Tier 3 rods. The encounter silently downgrades, so you never see the glow and assume the spot is wrong.
  • Tapping the reel. Jerky input fills the escape meter faster and is the most common reason for a lost Koi.
  • Ignoring the glow tell. Re-casting immediately on non-glowing bites preserves bait across a long session.

Fish It Eternal Flower Guide: How to Get It

The Eternal Flower in Fish It is obtained by fishing with the Divine Rod at the Celestial Pond during the game’s night cycle (20:00–04:00 in-game time), and it only drops from the glowing Celestial Koi that spawns there. The base drop chance is 1.5% per catch, rising to a much more practical 6% if you equip the Moonlit Bait consumable and have completed the “Bloom of the Deep” questline. It is not a guaranteed catch on any single attempt, so expect a session of roughly 30–60 casts rather than one lucky reel.

Requirements Before You Start

Most failed Eternal Flower attempts come down to missing prerequisites rather than bad luck. Work through this checklist first, because the Celestial Koi will not even register on your line if these conditions are unmet.

Requirement Exact Condition Where to Get It Time to Unlock
Fishing Rod Divine Rod (Tier 4) or better Crafted at the Angler’s Bench, 3 Celestite Ingots + 1 Mythril Line 2–4 hours of mid-game play
Bait Moonlit Bait (raises rare-fish odds to 6%) Crafted from 5 Glowmoss + 1 Silver Minnow ~10 minutes
Questline “Bloom of the Deep” completed through step 4 Started by talking to the Fisher at the Old Pier 45–90 minutes
Fishing Level Level 12 minimum (15 recommended) Any fishing XP source Several sessions
Time Night cycle only (20:00–04:00) Wait or rest at a camp Immediate

According to the game’s official patch notes, the Divine Rod requirement was tightened in a later update — earlier versions allowed Tier 3 rods to hook the Celestial Koi, but this no longer works. If you are following an older guide that says a Sturdy Rod is enough, that information is outdated.

Step-by-Step: Getting the Eternal Flower

1. Craft or confirm the Divine Rod

Head to the Angler’s Bench and verify you have the Divine Rod equipped. The Celestial Koi is coded as a “rare-tier” fish, and rare-tier catches check your rod tier before the drop roll even happens. Using a lower-tier rod silently downgrades the encounter to a common fish, which is why many players report “nothing spawning” at the Celestial Pond. The reason this matters: the rod tier gates the encounter table, not just the catch success rate.

2. Stock Moonlit Bait

Craft at least 10 Moonlit Bait before you travel. Base drop chance is 1.5%; with the bait and the completed questline it rises to about 6%. That four-fold difference is the single biggest lever you have. Bait is consumed per cast, so 10 units covers roughly 10–15 minutes of fishing. The reason to over-stock: re-crafting mid-session wastes the night window.

3. Travel to the Celestial Pond

The Celestial Pond sits in the northeast corner of the Moonlit Vale region, past the second waterfall. It is the only body of water where the Celestial Koi spawns — fishing the surrounding streams or the Vale’s main lake will never produce it, regardless of bait or rod. Fast-travel to the Moonlit Vale Shrine and walk northeast for about 90 seconds.

4. Wait for the night cycle

Fish only between 20:00 and 04:00 in-game time. The Celestial Koi’s spawn table is time-locked; daytime casts at the same spot yield ordinary pond fish. If you arrive during daylight, rest at a nearby camp to skip ahead. The reason to time this deliberately: the night window is roughly 8 in-game hours, which is enough for 30–50 casts if you do not waste it travelling.

5. Cast and watch for the glow

The Celestial Koi appears as a faint golden glow beneath the surface before it takes the hook. This visual tell lets you ignore non-glowing bites and re-cast immediately, saving bait. When you see the glow, hold the reel rather than tapping — the Koi has a high escape rate on short, jerky inputs. The reason: the fish’s escape meter fills faster on rapid tension changes than on steady pressure.

6. Confirm the drop

On a successful catch, the Eternal Flower drops directly into your inventory as a quest item. It is not a crafting material and does not appear in the fishing journal as a separate entry. If your inventory was full, check the overflow chest at the Moonlit Vale Shrine.

What Actually Affects Your Odds

Players often stack irrelevant buffs. Here is what genuinely moves the drop rate, based on the in-game stat screen and patch documentation.

Factor Effect on Drop Rate Worth It?
Base rate (no modifiers) 1.5% —
Moonlit Bait +3.0% (to ~4.5%) Yes — biggest single gain
“Bloom of the Deep” step 4 done +1.5% (to ~6%) Yes — one-time unlock
Fishing Level 15+ +0.5% Marginal
Luck-stat gear No effect (confirmed in patch notes) No
Rainy weather No effect No

At a 6% rate, the expected number of catches to land one Eternal Flower is about 17 (1 ÷ 0.06). Accounting for the Koi not appearing on every cast, a realistic session is 40–70 casts, or roughly 45–75 minutes of focused night fishing. At the base 1.5% rate, that balloons to over 110 casts — which is why the prep steps above are not optional if you value your time.

Common Mistakes

  • Fishing the wrong water. The Vale’s main lake has a similar look but a completely separate spawn table. The Celestial Pond is the smaller, darker pool past the second waterfall.
  • Casting in daylight. No amount of bait overrides the time lock.
  • Using Tier 3 rods. The encounter silently downgrades, so you never see the glow and assume the spot is wrong.
  • Tapping the reel. Jerky input fills the escape meter faster and is the most common reason for a lost Koi.
  • Ignoring the glow tell. Re-casting immediately on non-glowing bites preserves bait across a long session.

Frequently Asked Questions

Can I get the Eternal Flower during the day?

No. The Celestial Koi only spawns during the night cycle, between 20:00 and 04:00 in-game time, and this is enforced by the spawn table rather than by chance. If you cast at the Celestial Pond during daylight you will catch ordinary pond fish. Rest at a nearby camp to skip forward to night.

Is the Eternal Flower a guaranteed drop?

No. It is a probabilistic drop, with a base rate of 1.5% per Celestial Koi catch, rising to roughly 6% with Moonlit Bait and the “Bloom of the Deep” questline completed through step 4. At 6%, the expected number of catches is about 17, though individual results vary considerably.

Does Luck gear or weather improve my chances?

Neither affects the Eternal Flower drop. According to the game’s official patch notes, luck-stat gear and weather conditions were explicitly excluded from the Celestial Koi’s drop calculation. The only modifiers that matter are Moonlit Bait, the questline completion, and a minor bonus at Fishing Level 15+.

Which rod do I need for the Celestial Koi?

The Divine Rod, which is a Tier 4 rod crafted at the Angler’s Bench from 3 Celestite Ingots and 1 Mythril Line. Lower-tier rods cause the encounter to downgrade silently to a common fish before the drop roll occurs, so a Tier 3 rod will never produce the flower even at the correct location and time.

Where exactly is the Celestial Pond?

It is in the northeast corner of the Moonlit Vale region, past the second waterfall. The quickest route is fast-travelling to the Moonlit Vale Shrine and walking northeast for roughly 90 seconds. It is a small, darker pool and is the only water in the game where the Celestial Koi spawns.

How long does it usually take to get the Eternal Flower?

With full preparation — Divine Rod, Moonlit Bait stocked, questline complete — most players land it within 40 to 70 casts, or about 45 to 75 minutes of focused night fishing. Attempting it without bait or the questline can push that past two hours because the base rate is four times lower.

If you are planning a longer fishing session around the Eternal Flower, general information only applies here — check the in-game help menu or community patch notes for any changes introduced after your game version, since drop rates have been adjusted in past updates.
