The Tactical Plague Engine is a craftable post-Moon Lord summon weapon. When used, it summons a Plague Jet minion that fires and consumes bullets. It will attempt to fire from above, and will occasionally fire homing missiles instead of bullets, which inflict the Plague debuff. Additionally, it will always align itself horizontally when idle.
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 Tactical Plague Engine has over a Ruthless one is knockback.
- This summon weapon can be used to great effect when paired with Ichor Bullets as it can inflict Ichor on enemies without the player having to switch weapons.
- However, as the minions shoot quite fast and do not have a chance to not consume ammo, this can be quite expensive.
