Crystal Guardian

The Crystal Guardian is a resource node/mob introduced to Booga Booga in the Magnetite update.

It floats across the island, moving around the edge of the island in a set pattern. It can only be killed with a Crystal Pickaxe or greater tiers.

In order to open the Crystal Bridge to the third island, you need to mine this and drag(or pick up and drop) the Spirit Key in the Spirit Lock, which opens the way to Crystal Island, which was the only main way to get Crystals until the Emeralds Update.

The Crystal Guardian will respawn 10 minutes after being mined.

Location
The Crystal Guardian is located on the Sun Island, and it moves around the island until destroyed by a player.

Drops

 * 1 Spirit Key
