For Catch A Monster Patch 0.40, check the current codes page first, then prioritize the rotating dungeon route, the Lampyr Evolution event, and the Vectra Ball. Vectra Ball is the standout event prize because the video shows 2.5 catch chance plus 30% mutation chance; Gender Swap Potion is limited in the event board; and the new rotating dungeons create a separate boss/reward loop with attempts that refresh.

Step-by-step

Follow the in-game plan

Use the video as the walkthrough, then use these notes as the practical checklist.

Start with current codes, not old patch memory

Patch 0.40 includes visible patch-note codes and secret codes in the video, but Catch A Monster code windows move quickly. Use the live codes page first, then try video-era codes only when they are still supported by current checks.

  • The video shows DJEMBE and FESTPUN in the patch notes.
  • The video also calls out EGEXOS and LOLTEEG as secret or known codes at recording time.
  • Use the current codes page before relying on a one-video snapshot.

Treat rotating dungeons as a new boss loop

Rotating dungeons add timed difficulty choices with separate rewards and attempts. The first boss shown in the video restores 3% max HP per second, which makes the later Solgryph guide the practical next watch for players who cannot burn it down.

  • The video shows Inferno, Nightmare, and lower-tier reward options.
  • Failed attempts do not appear to spend successful-clear attempts in the recording.
  • Use the Solgryph/Violet Aegis guide for the deeper boss strategy.

Prioritize Vectra Ball if mutation farming matters

Vectra Ball is the clearest event prize from the update because Cyclone9 shows 2.5 catch chance and plus 30% chance for all mutations. That makes it a strong target for players who farm mutated pets, mutation fragments, or rift-party catches.

  • The Vectra Ball is shown as a grand prize event reward.
  • The video shows plus 30% chance for all mutations.
  • Do not skip the event if mutation farming is part of your account plan.

Use Lamp Tokens and the exchange shop efficiently

The event lets players earn Lamp Tokens from monsters, bosses, rifts, and dungeons, then use the reward board. Cyclone9 also shows an exchange shop refresh that can turn saved materials into more tokens and more rolls.

  • Farm monsters, bosses, rifts, and dungeons for Lamp Tokens.
  • Check the exchange shop every refresh if you have stocked materials.
  • The video frames a full exchange refresh as enough for 30 rolls.

Save Gender Swap Potion until breeding rules are clear

Pet gender swap is powerful because breeding outcomes depend on male/female roles, but the video treats the event Gender Swap Potion as limited and valuable. Do not use it casually before deciding which S or SS pair actually needs it.

  • The event board shows only two Gender Swap Potions available in the recording.
  • The Pet Center has a gender swap tab after Patch 0.40.
  • Wait for a real breeding plan before spending rare gender swap items.

Use quality-of-life changes to farm cleaner

Trait auto-sell, visible offspring EM, breeding bonus settings, and the gear attribute gallery all reduce guesswork. The safe route is to use these tools while avoiding claims the video does not confirm, such as whether evolved offspring inherit parent EM values.

  • Trait auto-sell can remove lower-value traits while farming.
  • The pet index calculator now includes breeding bonus settings.
  • The gear attribute gallery shows details such as Life Siphon's recorded 10% lifesteal effect.

FAQ

Catch A Monster Patch 0.40 guide questions

Quick answers for the route, materials, mechanics, and next steps covered in the video.

What is new in Catch A Monster Patch 0.40?

Patch 0.40 adds daily rotating dungeons, the Lampyr Evolution event, Vectra Ball, pet gender swap, trait auto-sell, breeding interface improvements, Nova Coast achievements, new pet collection content, Spire and shop price reductions, gear attribute details, and new codes.

What does Vectra Ball do in Catch A Monster?

Cyclone9's Patch 0.40 video shows Vectra Ball with 2.5 catch chance and plus 30% chance for all mutations, making it a strong event target for mutation farming.

How do you get Lamp Tokens in Catch A Monster Patch 0.40?

The video says players can get Lamp Tokens by defeating monsters and bosses and by clearing rifts and dungeons. The exchange shop can also convert stocked materials into more tokens on refresh.

Should I use Gender Swap Potion right away?

No. Cyclone9 treats Gender Swap Potion as rare and breeding-relevant, so save it until you know which male/female S-rank or SS pair actually needs a swap.

What codes are shown in the Patch 0.40 video?

The video shows DJEMBE and FESTPUN in the patch notes and calls out EGEXOS and LOLTEEG as known or secret codes at recording time. Because codes expire quickly, use the current Catch A Monster codes page before depending on those video-era codes.

How do you beat the new rotating dungeon boss?

Use the dedicated Solgryph rotating dungeon boss guide. The short version is that Violet Aegis restores 3% max HP per second, so you need Solgryph burn stacks, stun support, and a strong party.
