Backline

The backline is the first (and often only) line of defense in any attack formation. It is usually populated by support roles such as monks and necromancers. The usual distance of the backline from the frontline is the the spellcasting radius.

Most formations have three distinct lines, viz., a midline separating the front and backlines  populated by offensive spellcasters who can reach past the enemy frontline. However, two line formations where the back and midlines are combined are also seen; these formations are sometimes called collapsed backline formations.

In builds that have units who do not need to stay in spellcasting radius, it is possible to have a second defensive line after the backline. This second line is populated by such roles as Heal Party spammers, "Orders" necromancers, and "bonder" monks.
