Unnatural Disaster

Unnatural Disaster is a Squad Mission in Xenoblade Chronicles X which is unlocked during BLADE Mission No. 20 along with The Old Adage after the squad collectively collects five Myuena Cacti.

This mission involves fighting a gigantic Colubrim in Cauldros, but without any Skells to help, unlike in the Squad Mission Legendary Drake. This Colubrim is similar to Vortice, the Deific Blast, so it's going to be a difficult fight. Additionally, three Scintimures fly near the colubrim, although they won't join unless the player gets close to them.

While brimstone does rain from the sky, it is possible to stop the damage by making a U-turn onto the ramp leading up to the pillar above: there's a Weather-Altering Device above that can change the weather to Clear.
