The Endogenesis is a craftable post-Moon Lord developer summon weapon. It summons an ascended ice construct that has four different modes:

  • Endo Cooper will fire five to seven lasers that will infinitely pierce in the direction of nearby enemies.
  • Endo Cooper will launch out several homing icicle shards.
  • Endo Cooper will aggressively ram back and forth into enemies.
  • Endo Cooper will fire endothermic flamethrowers in all directions.

Each mode is toggled by resummoning the Endo Cooper. All attacks except the laser inflict the Exo Freeze, Glacial State, and Frostburn debuffs. Each summon requires 10 minion slots to be summoned and only one can be active at once.

Its best modifier is Ruthless. The Mythical modifier provides the widest array of stat bonuses, but these primarily affect the initial summon rather than the resulting minion. Additionally, minions cannot deal critical hits. The only lasting advantage a Mythical Endogenesis has over a Ruthless one is knockback.
