Tower (Swarm)/1.03.25

Swarm
The Swarm's tower has a low damage amount, but it possesses a rare to find magic type. As nothing in the game has any armor to magic (though some units have a special resistance to it), it will always be hitting for full damage, ensuring that even the most toughest of opponents can be cracked. However, the low damage amount does mean that weedy units that don't normally have any armor will still be hit for the same, low damage, making the towers only really effective at hitting tough, armored units.

The building's heavy cost of gold clashes with Scarabs' heavy cost of gold, too. Although, the Scarabs could be placed into the towers to beef up that poor damage amount, in doing so, you'll be making The Swarm's easy to exploit terrible air defense even more exploitable, as well as generally weakening their effectiveness against elite infantry and the many units in the game that have a fire resistance.
