  • Nezkrov

    Very nice ! Thanks for the walktrought ! But.. what QL is recommended for this mission ? ?

    • Vikinger

      Dunno about the QL but you need to be at least rank 6 whit your faction to be able to take the quest.

    • ninjafada

      done QL10 green/blue lost 3k hp against the boss

  • Toby Wong

    i’m QL 10 elemental, 7 AR, 5 talismans. very last fight gave me trouble and just had some lowbie at the junkyard help heal me.

  • Had no issues with this. Breezed through it. Mind you I did start on day 1 and I have a solid solo strike build

  • Bonez

    I did this QL 6 AR while standing on the cars…. Took a very very long time spamming “Anima Shot”. Had to use “Shot of Anima” as well on the last boss fight.

  • Slacker99

    Did it with a QL5 AR. Grabbed golems and pulled them out to road through last barricade defended in earlier quest. Non-torchcutter golems are easiest to kite in circles in the open road. Last boss was a pain for a lowbie, had additional nurture heal with QL5 fist and drank 2 QL5 heal drinks. Stay as far away as possilbe, especially during AOE boss cast.

    Tried as QL5 chaos / QL5 fist, but too close to golems to escape damage. Used some SP/AP to get AR and inner ring skills. Dunno how much AR QL made a difference, maybe could have gone lower. Glanced a lot.

    Reward is a QL10 quantum device. Need to spend 35SP and 50AP before it is useful.
