"No foe can escape the Archer's arrows. This tower has a special switch - choose long range or fast attack!"
Long Range Mode
Fast Attack Mode
The Archer Tower is a defensive building that can target both air and ground units. This building is unlocked at Builder Hall level 2. Like the Home Village Archer Tower, it is a single-target defense.
The Archer Tower can be set to Long Range or Fast Attack. Both modes has its advantages and disadvantages.
The Long Range mode gives the Archer Tower a range of eleven tiles, at the cost of DPS. It has the lowest DPS of any single-target defensive building at relative level in this mode.
The Fast Attack mode gives the Archer Tower additional damage output by firing twice as fast as the Long Range mode. This comes at the cost of range - even as its range is reduced by four tiles, it covers only about 40% of the area that a Long Range Archer Tower would cover.
When upgrading, an Archer Tower's damage per second increase of Fast Attack is twice as much as the damage per second increase of Long Range so Fast Attack is always twice the DPS of Long Range.
The Master Builder can go to your Home Village and gear up an Archer Tower that is level 10 or above in order to allow it to toggle between Long Range and Fast Attack modes, which requires Town Hall 8. This requires a level 6 Archer Tower in the Builder Base, which is at Builder Hall 6. Like with other gear ups, only one Archer Tower can be geared up.
The Archer Tower in fast fire mode in the Builder Base has the same attack speed as a normal Archer Tower in the Home Village.
An Archer Tower that is set to Fast Attack cannot protect buildings in front of it. However, it is more effective at taking down tank-units, and they are more able to handle small swarms of Bats or Skeletons in this manner.
You can protect Archer Towers with splash damaging defenses like the Crusher since it is a single-target defense.
Try to swarm the Archer Tower with swarm units such as Raged Barbarians as it is single-target.
Use tanks like Boxer Giants to distract it so that supported troops can take down outer buildings.
Long-range Archer Towers have fairly low damage output, taking three shots to kill equivalently-leveled Sneaky Archers or Beta Minions. If you use Sneaky Archers or Beta Minions to snipe buildings and there are no more unprotected buildings, choosing buildings protected only by a single long-range Archer Tower will give your troops the most time to attack before they are destroyed.
The Archer Towers undergo significant visual changes at all levels except level 2.
At level 1, the Archer Tower is a basic wooden tower tied up with ropes, partially inside a square hole in the ground, with a lever next to it.
At level 2, the Archer Tower's platform gains extra planks on its edge. The composition of the beams inside also change. The platform gains a low wooden railing on all sides.
At level 3, most rope ties are gone and the hole in the ground is surrounded by stone, and the lever gains more substantial housing.
At level 4, the top platform's edges are reinforced with a copper band. The beams and ropes are in new locations.
At level 5, the rest of the ropes disappear and are replaced by riveted metal fittings and the copper band becomes gray metal.
At level 6, the top platform's corners are covered with copper plates. The corners of the base gain additional stone bricks.
At level 7, the top platform is now made of stone; its corners are now blue-gray metal, and its edges are completely metallic as well. A blue gear can be seen near the base of the tower.
At level 8, the corners of the tower are now golden, as are some of the nails on the tower. A golden band is present on the perimeter of the tower as well.
At level 9, the gold on the corners become larger and the base is now thicker and stronger. The lever is removed from the side.
The Archers on top of the Archer Tower change their appearance as you upgrade the Archer Tower. The Archers that are on top of the tower appear to be Archers from the Home Village instead of Sneaky Archers.
When initially constructed, the Archer Tower stations a single Archer that appears to be level 1 (or 2).
When upgraded to level 4, the Archer atop the tower resembles a level 3 (or 4) Archer.
When upgraded to level 6, the Archer atop the tower resembles a level 5 Archer.
When upgraded to level 7, a second Archer appears.
When upgraded to level 8, the Archers atop the tower resemble a level 6 Archer.
The Archer Tower is currently the only defensive building in Builder Base that has two modes, which are Long Range and Fast Attack.
Like other buildings from Builder Base that are equivalent to the Home Village, the Archer Tower in Builder Base has more damage and hitpoints than the Archer Tower from the Home Village.
Unlike other buildings from Builder Base that are equivalent to the Home Village buildings, the Archer Tower, Walls and Army Camp in Builder Base have their own design.
The Archer Tower likely has its own design because the tower itself has a system where it can be set into different modes.
