"Bathe foes in a fiery flood of scalding plasma! Both air and ground troops will feel the burn!"
The Roaster is a Defensive Building in the Builder Base that is unlocked at Builder Hall level 6.
It shoots short plasma bursts at its enemies that deals splash damage. Its damage per hit is very low but the high fire rate makes up for it.
It can burn both air and ground troops.
Use the Roaster as an outer defense as it does not do as much damage against tanks but can do a lot of damage to swarms.
A full burst of 15 hits will be enough to kill Raged Barbarians of relative level.
Try to put units with a lot of hitpoints in front of support units with less hitpoints to distract it from shooting the support units.
Try to separate the troops so it does not hit every troop.
At level 1, the Roaster looks like a metal vessel secured by wood planks that are tied up by ropes.
At level 2, the ropes are replaced by a plank rim.
At level 3, the wooden frame is replaced by two fences.
At level 4, the lower part of the vessel turns red and a ladder leading to the muzzle of the vessel.
At level 5, the fences are replaced with a stone rim.
At level 6, the stone rim get another layer and the ladder is replaced by metal one.
