To unlock the territory containing the War Factory, you need a Level 15 Radar as well as 93 map regions revealed.
As a Hero, she does not require time or Gold to train. If she is defeated in battle, she will reappear in the Hero Hut after the battle, fully healed and ready to fight again.
In battle, she is a long-ranged attacker with moderate health and DPS.
Her Hero Perk is Robot Overlord, which causes her to spawn groups of critters every few seconds.
She spawns 3 critters every few seconds. Once there are a total of 12 on the battlefield, she stops spawning further critters until at least one of them are destroyed. She resumes spawning Critters once the number of Critters fall below 12; in the cases when there are 10 or 11 Critters spawned, she will spawn enough to make 12 once again. Critters fired from the Gunboat or produced from Critter Swarm do not count towards this total.
Hero Abilities
Similar to Gunboat Weaponry, Hero Abilities can be used during battle at the cost of Gunboat energy. Your hero can only have one ability active in a battle. The ability can be fired more than once, but the energy cost increases each time. The following are the three abilities available to Cpt. Everspark. Click one to read more about it.
The critters that the hero spawns can be useful for distracting single-target defenses like Boom Cannons as long as there are no splash defenses such as Flamethrowers nearby.
As she has the longest range out of all heroes, she is more compatible for Tank-based armies. Unlike Brick, she can comfortably stay behind Tanks which means she is less vulnerable to enemy fire.
Each upgrade increases Cpt. Everspark's hitpoints by 6%, damage per second by 6%, and increases Critter spawn rate by reducing time to spawn by 0.1 seconds.
Everspark's effective damage per second is actually about a quarter of what the game implies, as she loses most of her time "searching" for Critters to deploy.
