Alarm Bell

The Alarm Bell only has one function in your Lordrush Town: to determine the role of your Residents in the defense of the Town. There are two choices: Warrior and Archer. The Warriors will engage invaders in close-range combat while Archers will engage from afar.
Ignore the game’s recommendation of an even split between Warriors and Archers. Instead, set them to all Archers. This will keep them safe from the opposition, which means you won’t have to wait for new villagers to arrive if they fall, meaning your production buildings like the Sawmill or Iron Mine will not stay underutilized while you wait.
There are no upgrades to this building and it can pretty much be ignored after your first week or so in your Lordrush journey.
This building has no upgrade levels.
