Details: The Worker has a variety of abilities. He is able to repair damaged structures such as the castle doors in addition to being able to build entirely new structures (including ones for easy entry into the enemy’s castle) if resources are sufficient.

He can also harvest wood and metal by locking on to trees or rocks containing ore and either chopping or using a more powerful charging attack. These resources can be used to build new structures or upgrade hat machines. In addition to wood-chopping, the Worker’s axe can be used for melee attacks against enemies.

Upgrade: Once upgraded the worker gains a nifty square hat, but more importantly a throwable bomb.  The longer you hold the attack button, the more damage the bomb will do, but its accuracy seems to decrease.

Workers have a low amount of health but move quickly.

When workers team up to build machines, the time it takes to build is dramatically lessened. The upgraded worker machine drops large bombs which can be used by anyone.

Tips: When chopping wood or mining crystal, 2 charged hits are faster than tapping square.

Harvest crystal first. Wood is easy to obtain and close to your base.  Try to capture a tower near crystal fields and get as much as you can.

I always play worker first until everything is upgraded, or until I get the important stuff upgraded. (like dark priest
