Unlocks Fists of Lava

Upon completion of the Zuri Karatachi “Fists of Lava,” quest, you are now able to begin progression for Volcanic Eruption. For Volcanic Eruption, you are required to have Fists of Lava and run on the lava located in the Karatachi Volcano for ~20 minutes during a permanent death event. The most recommended area to do this during a permanent death event is the lava located around Bastion Karatachi. This area of lava allows you to run in a circle, which is most optimal for running on lava for a prolonged period of time. You will receive many lines of dialogue during the progression, when you start receiving lots of “…” messages you are almost done. Video Demo
