"After spending too long alone on the island, Sgt. Brick is ready to fight the Blackguard for real again."
Sgt. Brick is a Hero that aids you in battle with her abilities.
When you upgrade your Headquarters to level 4, you will have the ability to rebuild the Derelict Hut in the corner of your island. Doing so will unlock Sgt. Brick.
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 combat, she is a ranged attacker who fires rapid sprays of bullets from her rifle. She can fire 15 shots before having to reload.
Her Hero Perk is Grenade Spammer, which causes her to fire a grenade every time she shoots at a new target to deal heavy damage.
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 Sgt. Brick. Click one to read more about it.
As many of Sgt. Brick's abilities buff troops in a large area, she works best with armies that are composed of many troops, such as Heavy-Zooka. With a larger amount of troops, the overall effectiveness of her abilities is increased.
It is generally not a recommended idea to use her with Tanks. Her shorter range means that defenses are likely to fire on her first, reducing the amount of time she is active.
Each upgrade increases Sgt. Brick's hitpoints by 8%, damage per second by 10% and Grenade damage by 8.2%; level 22 to 23's increments are slightly larger than these.
