(Desktop, Console and Mobile versions) The Staff of Earth in action. Note how it deals more damage the faster the projectile.

The Staff of Earth is a Hardmode, post-Golem magic weapon that launches a Jungle Temple-style boulder that is affected by gravity, bounces off of tiles and rolls on the floor, and can pierce enemies five times before breaking upon the sixth hit. It continues damaging enemies on contact while it rolls on the ground. The boulder's base damage and knockback depend on its velocity (see details below). (Desktop, Console and Mobile versions) The Staff of Earth also has a base 24% critical strike chance, as opposed to the usual 4%. The Staff of Earth has a (Desktop, Console and Mobile versions) 1/7 (14.29%) / (Old-gen console and 3DS versions) 1/8 (12.5%) chance to be dropped by Golem.

Its best modifier is Mythical.

[math]\displaystyle{ \text{damage} = \left\lfloor d * \frac{1}{30} * \text{velocity}_{\text{tiles/second}} \right\rfloor }[/math],
which is roughly equivalent to
[math]\displaystyle{ \text{damage} = \left\lfloor d * \frac{11}{450} * \text{velocity}_{\text{mph}} \right\rfloor }[/math],
with [math]\displaystyle{ d = 45 }[/math].
The base damage can never go below 5.
The following table lists some exemplary values:

  • Boulders can be cast through one-block walls when standing directly adjacent to them.


  • One way to achieve top velocity for maximum damage is to fire boulders from above, downward.
  • The boulder's high damage and piercing, along with its ability to roll on the ground, makes it extremely effective when deployed as ground-based crowd control.
    • (Desktop, Console and Mobile versions) The quick use time also makes it a viable weapon for inflicting high single-target damage.


  • Desktop
    • Item and projectile sprites updated.
    • Drop rate increased from 1/8 (12.5%) to 1/7 (14.29%), due to the Picksaw now dropping separately.
    • Now lists "max speed" damage rather than "low speed" damage.
    • Now only has two velocity thresholds that affect damage (and now additionally knockback) instead of direct dependency.
    • Increased critical chance from 4% to 24%.
    • Mana cost increased from 15 to 18.
    • Use time decreased from 40 to 24.
    • Projectile speed greatly increased.
