A very fragile unit that excels at super long-range splash damage in a large area. It is unable to attack units that are in close range to it.
Values are normalized to the supply cost of the unit to make it easier to compare units.
The Splash Index tries to calculate the effectiveness vs spam by multiply attacks with slash area and a penalty for damage below 350.

The Stormcaller is a fragile, long-range artillery platform designed to decimate groups of enemies from a distance.

The Stormcaller's rocket barrage is unique in that it deals substantial damage both to single targets and to chaff units, enabling Stormcallers to cripple or outright kill grounded units too slow to evade its attacks. A few units of Stormcallers deal enough single-target damage to threaten even giant units, and the AoE on its rockets become more useful in later rounds, where there are more and more units that could potentially be hit by a rocket volley. While the Stormcaller possesses incredible damage potential, it also has a number of weaknesses. Stormcallers fragile and can't attack adjacent units, meaning that units like Crawlers and Rhinos that can get inside its attack range will destroy them. Stormcallers have no way to attack air units and require anti-air support, and their rockets can also be shot out of the air by Mustangs with Missile Interception, severely limiting the Stormcaller's damage output until the Mustangs are destroyed.

As a general rule, 3 units of Mustangs will consistently intercept the missiles of 1 unit of Stormcallers - if you have more Stormcallers, eventually some of your rockets will successfully land. Like all fragile units with long range, Stormcallers are threatened by any unit that can outrange it due to their fragility and low fire rate, though this would require the Range Enhancement tech upgrade to achieve.

Though the Stormcaller has a powerful attack, the rockets it fires are unguided and take a while to reach its destination. Fast units such as Crawlers, Rhinos, and Steel Balls are naturally fast enough to outrun Stormcaller rockets, while slower units that have had their speed increased (e.g. Speed Specialist, Mechanical Rage) can evade some of the Stormcaller's rockets, noticeably decreasing its damage output. The rockets also have a low accuracy and spread the damage over a wide area. Against shields and giants this is no problem but smaller units only get hit by a few rockets.

The Stormcaller has no defensive upgrades - it's tech upgrades solely focus on increasing its damage. Range Enhancement is key for when the enemy commander begins deploying long-range units of their own (e.g. Fortresses, opposing Stormcallers), while Armor-Piercing Anti-Tank Shells let Stormcallers more effectively take down giant units or shields. Stormcallers are also one of the more reliable ways to disable enemy tech upgrades with Electromagnetic Explosion thanks to their long range and area of effect.
