Crystal Bridge

The Cyrstal Bridge was able to be unlocked with a Spirit Key to grant access to the 3rd Floating Island. In order to activate the bridge, a Spirit Key was required to open the Spirit Lock. This would use the player's key to form the Crystal Bridge. Previously, the Crystal Guardian dropped the Spirit Key. On the 3rd Floating Island is the Lonely God and Crystal Lodes, along with Petrified Bushes and Petrified Trees.

After summoning the bridge, the structure will disappear in about 60 seconds.

Tips

 * It was used to be able to place docks ontop of the bridge, but the glitch was patched.
 * Don't stall, because the bridge will disappear pretty fast.
