Tower Spotlight: The Tesla Tower
The Tesla tower, named after inventor Nikola Tesla, hits nearby enemies with a powerful electric arc that can jump from enemy to enemy. At level 4, the Tesla tower can target flying units.
Pro tip: Build a Shrink tower near a Tesla tower whenever possible, as they pair well together.
