The Crystal Towers are five towers (the Amethyst, Emerald, Ruby, Sapphire, and Topaz Towers) that spawn for limited-time events. Killing them is required to summon and fight The Keyper.

After all Cyclops Gods in a Realm have been slain, the five towers will spawn in random locations around the Mountains and Highlands. Each of them will be marked on the minimap by a colored dot matching the tower’s color.
Each Tower is stationary and cannot attack directly. However, upon activation, they will spawn in a number of Crystal Cavern enemies corresponding to their color, which will defend it from attackers. The Crystal Towers heal their nearby minions at a rate of 300 HP every second.
Upon being defeated, they will become grey and inactive, despawning all of their minions. Once all five towers have been disabled, The Keyper will spawn in the Mountains.
After all Ent Ancients in a Realm have been killed, the towers will reactivate and respawn their minions. When defeated this time, the Towers and their minions will be destroyed for good rather than deactivated. Once all of them are destroyed, The Keyper will appear one last time.
All of the Towers’ minions are differentiated from the ones in the Crystal Cavern by having “Emergent” in front of their names. These Emergent variants of the enemies do not scale HP and have approximately halved projectile damage. The larger minions can also drop Stat Increase Potions respective to their colour, eg. Purple - Attack, Green - Speed and so on.
