Here’s the fast way to catch the seed in Toxic Grove in Fisch: fish in Toxic Grove itself, and do it in a toxic boil if one is active, because that boosts your odds. The item is extremely rare, so the real strategy is to maximize catch volume and use a Scavenger -style setup if you have it.

Where to get it

  • The seed comes from fishing in Toxic Grove , which is in the Lost Jungle region.
  • You usually need access prep first, including reaching the area and having the Gas Mask for the toxic section.
  • Some guides also mention a bestiary progress requirement before entering the deeper area.

Best farming method

  1. Go to Toxic Grove and fish repeatedly.
  1. Look for a toxic boil and fish inside it, since it improves the drop chance.
  1. If you can, use a rod with Scavenger , which increases your odds further.
  1. Keep fishing until it drops, because the item is very RNG-heavy.

Odds and notes

  • One guide says the seed has about a 1 in 2,000 chance normally.
  • The same source says toxic boils improve that chance, and Scavenger boosts it again.
  • Another guide says the item can appear as part of a catch, similar to a treasure-map-style drop.

Practical tip

If you want the shortest grind, combine toxic boil + Scavenger + fast fishing and just keep rotating spots in Toxic Grove until one appears.

TL;DR

Fish in Toxic Grove , prioritize toxic boils , and use Scavenger if possible. It’s a rare drop, so persistence matters more than anything else.
