Create a blazing wall of fire along a straight path.
This move is similar to the Butter Barrage, which is exclusive to Plants vs. Zombies: Garden Warfare 2. Its best use is to block an area of zombies to deal high damage to all that go through the path. It can also be used to trap zombies that are trying to escape from you. Block the exit and use Flame Blower to deal high damage to them.
It is not recommended to use this as a stand-alone attack, because it is easy for zombies to escape the trail if it is in an open area.
This ability has good synergy with attacks that restrict movement, like chilling and stunning, as these will make them stay in the trail even more.
