The Exo Mechs, also known as the Exo-Mechanical Exo-Beasts and the Magnum Opera, are a series of powerful Godseeker Mode bosses that the Calamity Mod adds to the game. They are machines designed to be difficult, boasting bosses with high stats, health, and damage. Every mech is more difficult than the last and best fought by designation number. The primary fights of each Exo Mech are summoned through different means, but individual mechs can be summoned using Exo Mech Summoning Items.
There are currently 7 Exo Mechs that can be fought.
