The Wraith path is one of two paths of the first major branch in the undead mage tree. Wraiths have the disadvantage of being single target units. To make up for this, they have an extremely high initiative and an immunity to weapons. They do a lot more damage than the other branch, and they can still hit any unit. They make great front line tanks as they are immune to all "weapon" damage, even tho they are classified as casters (watch out for enemy mage units tho, since these guys can disappear as fast as a wallet in New York). Due to their high initiative and damage output, the Wraith is an excelent counter to other casters, killing them before any chance of retaliation.
