Granite Control Staff

The Granite Control Staff is a Pre-Hardmode sentry. Upon use, it spawns a Granite Energy Core at the cursors location. The Core spins in place violently and shoots confusing projectiles at nearby enemies. It's range is rather small, so it's advised you place it in a convinient spot. The Core lasts for about 41 seconds before despawning.

It is made using 30 Granite and 3 Granite Power Cells at an Anvil.
