The Challenge 6: Alien Invasion is one of the easier Altrium farming quests. As the sixth of the Altrium quests, the Challenge 6: Alien Invasion doesn’t pose too much of a challenge and is well-suited for Sabers. Players can even opt to rely on pure raw power to mince through the incoming enemies.

  • The first wave of enemies of the Challenge 6: Alien Invasion are all Altonian and Lancer class in nature. For Saber class servants, this should be a walk in the park since Sabers beat Lancers. However, take this time to increase your noble phantasm gauge if you can chain Arts cards. Once you reach an acceptable amount (maybe around 60% would be fine) then, you can go on taking them down.
  • Once you take them down, you’ll head into the second wave of Challenge 6: Alien Invasion which has a Chimera waiting for you. Chimera’s are known for dealing heavy critical damage especially after they use their Roar Skill. Fortunately, unlike the Planet Free Quest, the Chimera here is alone and you won’t need to deal with other creatures. Bad news is though that the HP is humongous and it might take awhile to go down.
  • At this point, multi-hit noble phantasms may be a bit useless. Bring someone who has a single target Noble Phantasm. Doing so not only stops you from wasting time but at the same time focusing everything on a single enemy.
  • After defeating the Chimera, you’ll now be able to walk away from the Challenge 6: Alien Invasion with a little more altrium.
