Backwater Camp (背水の陣) is the nineteenth Challenge Quest. As healers cannot be deployed in this mission, there are two general strategies available to the player: rely on the DPS of ranged units, or rely on switching out a melee unit just before they lose all their HP.
For the purposes of this challenge (and other "No Healers" maps), units from healing classes are restricted: Healers, Shamans, Dragon Shamans, Bishops, Priest Warriors, Feng Shui Users, Druids, and Dark Priests.. Other units are okay, even if they have skills or abilities with healing properties.
Goblin Soldier ×8

- The original Japanese name for this mission, 背水の陣 (haisui no jin, "a battle formation with water to the back") is an expression referencing the famous Chinese military general Han Xin, where in one of his battles he intentionally fought with his soldiers' backs to a river, cutting off their own retreat and thus committing themselves to destroy the opposition to survive. It is equivalent to the English saying "fighting with one's back to the wall". No relation to any of the three current senses of the English word "backwater".
