The Diamond Staff is the strongest of the 7 gem/bar staffs. It does a high amount of damage, has a high fire rate, damage up to 2 enemies and has a low mana cost, making it a very good magic weapon early on. However, the materials are rather hard to collect. It is still effective well into Hardmode.
Its best modifier is Mythical.
- If your world generated with Gold Ore, you will have to make the Ruby Staff instead, unless you can gather enough Platinum Ore with the Extractinator, collect it from another world, collect it from slimes, or get platinum through fishing crates such as the Wooden Crate.
- The bolts fired from the Diamond Staff (and other gem staves, as well as the Spectre Staff) can pass through the slanted side of sloped blocks.
- 1.3.1: Sprite updated.
- 1.2.3:
- Damage decreased and mana use increased.
- Piercing was reduced to only 2 enemies.
- 1.2: Introduced.
