The Cosmic Viper Engine is a craftable post-Moon Lord summon weapon that is an upgrade to the Tactical Plague Engine. It summons a Cosmic Gunship that fires the following projectiles:

Projectile Description
Concussion Missile Concussion Missile An accurate fast missile that deals 150% of the weapon’s damage
Homing Rocket Homing Rocket An insanely fast homing rocket
Splitting Rocket Splitting Rocket An insanely fast homing rocket that splits into four shrapnels in random directions when getting close to an enemy. Shrapnels deal 25% damage.

Its best modifier is Ruthless. The Mythical modifier provides the widest array of stats bonuses, but these primarily affect the initial summon rather than the resulting minion. Additionally, Minions cannot deal critical hits. The only significant advantage a Mythical Cosmic Viper Engine has over a Ruthless one is knockback.
