Quetzalcoatl is the boss monster of Rock Nest Bottom. It's a huge serpent-like creature with wings that can be easily spotted because of the large dust cloud on its base. It has two simple attacks: a standard and a missile attack. Both attacks are relatively easy to evade and the missiles will not hit anyone close enough to the monster.
This boss has two special abilities, which at some point makes you unable to attack him. Has the ability to temporarily null your main weapon and advanced weapon for a few secs
