Important Fishing Tips for Toxic Grove
Fishing in this area is slightly different from normal locations.
Do Not Touch the Water
The water in the Toxic Grove is poisonous.
If your character touches the water, you will instantly die.
Always fish from safe ground or platforms.
Use the Correct Rod
Some rods work much better in this dangerous environment.
Recommended rods include:
- No Life Rod
- Seraphic Rod
- Oniflarx Rod
- Rod of Depths
These rods have strong luck and resilience stats, making rare fish easier to catch.
Invincible Enchant
If possible, use a rod with the Invincible enchant from an Exalted Relic.
This enchant helps prevent problems caused by the toxic environment and improves survival while fishing.
Use Fish Radar
Fish Radar can help identify spawn locations for some species in the Toxic Grove.
However, many fish still appear randomly, so patience is required.
How Long It Takes to Complete the Bestiary
Completing the entire Toxic Grove Bestiary usually takes:
3 to 6 hours
The time depends heavily on:
- Your rod’s luck stat
- Correct bait usage
- Weather conditions
- Random spawn rates
The Toxic Grove Bestiary is one of the first major progression milestones in the Lost Jungle update. Completing it helps players unlock new rods, quests, and access to later areas like the Living Garden.
By using the correct bait, fishing in the right conditions, and bringing strong rods, you can significantly reduce the time required to finish the Bestiary.
