Reach zone 165 for the first time
Reward Triple current run Helium for all zones completed until zone 165 (inclusive).
Goal Complete zone 165
All enemies have 5x attack and 2x health
Each time Trimps attack, they lose 5% of their health and receive a global stack (affecting all groups of soldiers) that reduces breeding speed by 0.3% (compounding) and increases all loot found and worker production by 0.15% (additive), stacking up to 1500 times.
These stacks are cleared when the player reaches the next zone.
"Travel to a dimension rich in helium, but also rich in toxic bad guys. All bad guys have 5x attack and 2x health. Each time you attack a bad guy, your Trimps lose 5% of their health, and toxins are released into the air which reduce the breeding speed of your Trimps by 0.3% (of the current amount), but also increase all loot found by 0.15%, stacking up to 1500 times. These stacks will reset when you clear a zone. Completing Zone 165 with this challenge active will reward you with triple helium for all Blimps and Improbabilities killed. This is repeatable!"

Helium challengeEdit

Toxicity is a Helium challenge. There are a few rules which are followed by each one of them:

  • The Helium reward from this challenge can be obtained repeatedly for multiple challenge completions.
  • Completing Toxicity will increase all Helium earned until zone 165 (including 165) by 3x.
  • Helium earned from completing Void maps will also be increased by 3x for each Void map completed on zone 165 or below. More information here.

Rules Edit

Note: The loot bonus from Toxicity stacks (explained below) also counts for Helium gains for killing Blimps and Improbabilities. That means the final Helium gain from Toxicity will be much larger than triple, depending on the length of your run.

For the duration of the challenge, all enemies have 5x more attack and 2x more health than they normally do.

A stack is gained each time Trimps attack. All stacks are cleared when players enter a new zone. Each stack:

  • Reduces Breeding speed by 0.3% (compounds down, similar to Geneticists)
  • Increases Loot found and worker production by 0.15% (additive, each stack is a flat percentage)

For a maximum of 1500 possible stacks per zone.

Each time Trimps attack they also lose 5% of their health, similarly to Nom.

With 1500 stacks, the player will gain 225% extra loot, and final breeding speed goes down to 0.01103x (1.103%), that means your breed speed will be divided by ~90.62 / you gain -98.897% penalty.

Note: Killing two enemies at once thanks to Overkill counts as a single attack. If you perfectly overkill an entire zone you'll only have a stack size of 50 instead of the 100 you would have had without overkill.
