Hartmut, the Calamity (Japanese: 大禍のハルトムート, Taika no Harutomūto) is a Tyrant in Xenoblade Chronicles X. It is a Millepod and can be found at level 91 around the cliffs in the western part of the Yawning Giant in Oblivia. It is the most powerful enemy in Oblivia. Killing it is required for segment recon. As Hartmut flies above a bottomless pit, Skells are all but mandatory to fight it. It is possible to wait for Hartmut to fly over to the land bridge near Mesa Fortress, but doing so takes a long time.
