Fish an Anime RNG September 2026 Update Notes
Three new rods, Complexity Mutation, Selene Store refresh, secret store event, and 15 active codes.
The 30 August – 2 September 2026 Admin Abuse + New Update dropped a major content batch for Fish an Anime RNG. Three new fishing rods shipped, the Complexity Mutation arrived as a rod-exclusive system, the Selene Store received new items, a secret store began spawning during certain events, and the active codes count stands at fifteen as of 7 September 2026. This page covers everything that shipped and what it means for your rebirth progression.
What arrived in the September 2026 patch
Three new fishing rods
The headline feature: three new fishing rods added to the plaza NPC. Community testing while the update was live established approximate stats, but exact rebirth gates and cash prices should be confirmed against the live UI — the patch recalibrated several shop values simultaneously.
The most discussed addition is the Complexity Mutation exclusive to one of the three new rods. Unlike standard mutations that apply a flat multiplier, Complexity Mutation stacks when triggered repeatedly on the same character. Each successive Complexity trigger raises the multiplier further rather than refreshing it. This makes the exclusive rod a long-term investment: the more you fish with it, the stronger mutated catches become.
The other two new rods fill mid and late-game gaps between Astral Rod and Void Rod, giving players at Rebirth 10–40 a meaningful upgrade path that was previously a stat cliff.
Do not dismantle your existing Void Rod or Astral Rod until the live plaza NPC confirms the new rods’ exact rebirth gates. Community screenshots from 1 September showed inconsistent stat displays during the first hours — a common post-patch artifact that resolved within 24 hours.
Selene Store refresh
The Selene Store received new items in this patch. Selene, the wandering NPC who spawns at semi-random locations around the map, now carries additional inventory compared to the August 2026 lineup. Specific items and rotating stock are still being catalogued by community researchers — we will update this section as confirmed data arrives.
If you are unfamiliar with Selene, read the gem shop guide for context on how her store differs from the standard gem shop and why players prioritise visiting her when she spawns.
Secret store event
A secret store now spawns during certain in-game events. It does not appear on the regular map — players report it only activates during specific triggers such as milestone celebrations or Admin Abuse windows. The secret store carries items not available in either the standard gem shop or the Selene Store.
Because the secret store is event-gated and its inventory may rotate, treat it as a bonus opportunity rather than a reliable shopping destination. Watch the official Discord (linked on our official links page) for spawn alerts during active events.
Character animations overhaul
Over 100 characters received unique animations in this patch — previously, many characters shared animation sets or had no distinct fishing idle. The visual overhaul is cosmetic but improves base readability: mutated characters with new auras are now easier to distinguish from standard catches at a glance.
Quality-of-life improvements
Patch notes referenced:
- Improved mobile UI responsiveness during pond fishing.
- Store code-box accessibility improvements.
- Reduced pond hitch and lag during eight-player server sessions.
- Rebirth cost display now rounds large numbers more legibly.
None of these are mechanical rewrites, but they address long-standing player pain points that accumulated in reviews and Discord feedback during August.

What the patch changed for your rebirth path
| Rebirth stage | Impact |
|---|---|
| Rebirth 1–5 | Cosmic Boxes from codes accelerate Lemon Stand save; no rod changes in this range |
| Rebirth 5–20 | Two new rods sit between Astral and Void; evaluate cost versus Void upgrade before committing |
| Rebirth 20–50 | Complexity Mutation rod becomes available; long-term stack scaling favours active farmers |
| Rebirth 50+ | Rod of Heaven’s still SSS; new rods do not displace endgame hierarchy |
Player checklist after the September patch
- Redeem all fifteen active codes via the Store menu.
- Open Cosmic Boxes during a Luck Potion window.
- Check the Fishing Rods NPC for the three new additions — screenshot stats before dismantling anything.
- Visit Selene when she spawns for the refreshed inventory.
- Confirm your carry is on the Lemon Stand, then claim Index gems.
- Review the mutations guide if you pulled a Complexity Mutation on the new rod.
Looking ahead
No official roadmap has been published beyond the 30 August patch notes. The secret store, Selene refresh, and Complexity Mutation suggest the development team is expanding event-driven and long-term progression systems rather than just adding content tiers. Watch Discord for October milestone codes and potential follow-up events.
We will add new update pages as confirmed patches arrive. For automation concerns, see the scripts hub — executors remain a ban-risk and are not recommended regardless of which rods you are farming.
