Gem staves

Gem staves are magic weapons that fire a brightly glowing projectile traveling at medium speed. There are 7 types corresponding to the 7 different gems. Higher-tier gem staves are capable of piercing one enemy. All gem staves, except the Amber Staff, are crafted from gems and bars at the Iron or Lead Anvil.

Notes

Not all ores can be obtained through mining in one single world. Only 4 of the 7 types of gem staves will be easily craftable in any given world; alternative metals can be had from a crate, bonus drops(Desktop, Console, Mobile and 3DS versions) from a slime, or Extractinator, but even all of these together represent quite low amounts of any given metal.
- This is not true on Drunk worlds(Desktop, Console and Mobile versions), as all ores generate on that seed.
In pre-Hardmode, the Amber Staff can only be obtained through materials produced with an Extractinator, killing Tomb Crawlers, opening Oasis Crates, or de-crafting items in Shimmer; as these are the only ways to get Sturdy Fossils before Hardmode. Prior to 1.4.0.1(Desktop, Console and Mobile versions), the Extractinator was also the only way to get Amber.
Like most other projectiles, the speed of a gem staff's projectile is affected by liquids.

Tips

Gem staves can be divided into tiers based on their strength and behavior:
- 1st tier lacks both autofire or piercing: Amethyst, Topaz, Sapphire. However, the Sapphire Staff can autofire on the Desktop, Console, and Mobile versions.
- 2nd tier has autofire and piercing: Emerald
- 3rd tier has high damage and fast speed: Amber, Ruby, Diamond
Their bright glow, reasonable mana cost, and auto-fire from the higher tiers make gem staves handy cave exploration tools.
A gem staff can be considered the magical equivalent of the Musket, being the first weapon of their class a player will often obtain and quite strong for when they can be obtained. Note that in the Desktop version, Console version, and Mobile version, the Wand of Sparking can be obtained prior to a gem staff.
