Venus Magnum

The Venus Magnum is a gun that is occasionally dropped by the Hardmode boss Plantera.

Arguably, it can be better at killing bosses in comparison to the Megashark, but is much more bullet-consuming due to not having an innate ability to save ammo. When ammunition efficiency isn't a concern, it may be better to use this over the Megashark due to its significantly higher base damage. The only downside is that it is not fully-automatic, which makes it more difficult to use to its full potential, compared to other hardmode weapons.

Musket Balls and Silver Bullets shot from this weapon gain the effects (but not damage) of High Velocity Bullets.

Trivia

 * The Venus Magnum's design isn't based on a nerf gun.
