The Emerald Staff attacking Target Dummies.

The Emerald Staff is the fourth-best gem staff, firing a bolt that can pierce 1 enemy.

It is the weakest gem staff capable of autofire, because its alternate-ore counterpart, the Sapphire Staff, does not autofire.

Its best modifier is Mythical.

If your world generated with Silver Ore, you will have to make the Sapphire Staff instead, unless you can gather enough Tungsten Ore with the Extractinator, collect it from another world, collect it from slimes, get tungsten through fishing crates, or transmute Silver Ore or Bars into Tungsten via Shimmer Transmutation or with a Chlorophyte Extractinator.

Due to its also somewhat slow projectile speed, this weapon suffers when facing moving aerial targets, such as the Demon Eye.
It will occasionally hit a target twice because of its slow projectiles and ability to pierce one enemy.
It is very useful for fighting hordes of enemies due to it not being obstructed after hitting at an enemy.
The bolt will travel at 41 mph until it hits an obstruction or enemy or goes off the map.
