How to Get Noxious Mutation in Fisch

Noxious mutation in Fisch is a rare mutation that decreases the sell value of the fish. Although it sounds useless, you will need it to unlock one of the best rods in the game, the Plaguereaver Rod. In this guide, we will tell you how to get Noxious Mutation in Fisch.

Noxious mutation can only be obtained if you are using the Toxinburst Rod in Fisch, a craftable rod that changes the appearance of the fish and makes them look purple with bubble particles.

The mutation reduces the value of the fish, and you get only 0.3x of the total amount. This makes it a bad choice if you want to farm money in Fisch. But if you want to unlock the Plaguereaver Rod in Fisch, you will have to craft it and use it to clear a few stages.

This rod has a 35% chance of applying Noxious to standard catches and a 15% chance of applying the Toxic mutation, which gives fish a 6x sell value. The rod also has a passive ability that grants Noxious Fish a 100% chance when it produces extra fish through its fungus ability.

How to Craft the Toxinburst Rod in Fisch

Find Olivia in Toxic Grove and complete her quest to get a Toxic-Proof Raft. The raft lets you navigate the region. After getting the raft, complete the following quests to collect all the required materials:

After collecting all four materials, you can head to the Ancient Archives and craft the rod for 185,000 C$.

Fisch Toxinburst Rod Stats and Ability

The Toxinburst Rod has a special ability called Fungus, which generates fungi that explode and grant extra fish with a guaranteed Noxious mutation. It has a 35% chance of applying Noxious to standard catches, giving fish a 0.3x sell value, and a 15% chance of applying Toxic, giving fish a 6x sell value.

Every 1 to 2 seconds, it bursts poison that increases the progress by 4%. It also generates one fungus every 20 to 40 seconds. Each fungus lasts 3 seconds and has a 20% chance to explode, granting 2 to 3 noxious fish before disappearing.

If you catch a fish, it activates propagation that lasts 1 minute. While active, catching more fish adds 20 seconds to its duration and increases its tier by 1, up to Propagation 50.

Each propagation tier increases the fungus spawn rate by 25% and the poisonous burst spawn rate by 2.5%. At Propagation 50, these bonuses can reach 1,250% and 125%, respectively. Here are all the stats of the Toxinburst Rod in Fisch:
