|Reach zone 115 for the first time|
|Reward||Perk: Siphonology and Electricity reward|
|Goal||Complete The Prison|
|All maps have an extra 300% additive to difficulty|
|All Electricity rules apply|
For the duration of this challenge, all maps get an extra 300% additive to difficulty.
This challenge has all of the rules from the Electricity challenge, which means it can be done multiple times for the double Helium reward; however, because this challenge is strictly harder than Electricity, there is no reason to do it multiple times.
Note that the difficulty increase also applies to unique maps, which will make The Prison substantially harder to complete.
During this challenge, the prison has 560% difficulty instead of 260%, which means to finish it the player should aim for combined health and block between 21.47Sp and 32.21Sp instead.
