Using Target Markers

Before the battle begins you can see who your mage and clerics are on the opposing faction and mark them as high priority targets. You can also fight a first skirmish to determine who the top healers are and take them out first in future skirmishes.

It is a good idea to know who your own healers are by marking them with low priority marks so you can see when they are being hassled by the enemy. Knowing who the healers are = win!
