Brimstone

"Yes, this vehicle comes with a big bada-boom! The Cluster Bombs it comes with can hit enemies at any range, as they fall down in a checker strike pattern. Combine that with the fact that they’re pretty tough, and you have a dangerous new unit to play with."

- 1.5 Patch

Overview
A premium artillery unit introduced in the 1.5 Patch costing, the Brimstone is an upgraded, more powerful stronger version of the Rocket Truck.

It has high health compared to most artillery units. It also has one of the strongest attacks, dealing 68-102 damage to every square it hits (in a checkered pattern).

At Rank 2, the Brimstone gains the Triple Strike attack, with the potential to deal 300+ damage to a single target, along with decent splash damage to surrounding squares with a slight chance to go even further out. However, it has a high unit value, so it will normally get matched with tanks in PvP battles.

An extra ability slot is unlocked at Rank 5, allowing it some flexibility in various battlefield situations.

Players with Brimstones are highly encouraged to invest some time to promote it a couple of ranks, and definitely should invest in Triple Strike. This attack is useful at later levels as well, since it will more than likely be able to shred on most enemy units in one hit. Furthermore, this attack can fire twice within 3 turns (only a one turn cooldown), which is much better than its checkerboard attack, since it can only fire once before reloading.
