Building in Fableborne means that you place towers and monsters on your island to make it stronger against other players trying to raid your base to steal your resources and gain trophies.
Make sure to protect your Island’s Heart, as it gives attacker the most amount of trophies.
To build, press the ‘Build’ button on your home base screen. From there you can purchase defensive towers, resource buildings and monsters by spending gold.
You can drop the newly purchased structure from your inventory and place is strategically on your island map.
By pressing 'Test' you can try out your newly updated base yourself.
