Healing Water is the fifteenth optional quest. It can be acquired by talking to Zalmo in Kalm. The player must travel to the southern Night Elf Encampment, Lothlorien, to fill a vial with the water of the Fountain of Restoration located there. However, when the player arrives at Lothlorien and talks to Feanor, they learn that the fountain has been defiled and must be purified - see quest Defiled Fountain. After doing so, the player can fill the vial and bring it back to Zalmo to complete the quest. Zalmo rewards the player with 800 Gold and 500 EXP.
When obtaining the quest, Zalmo mentions that if you help, the "ill child's parents may reward you greatly". However upon completion, the reward is handed to you by Zalmo himself.
