I held back a little of the water from Ashenvale, not because I doubted your ability to deal with the situation. Rather, I knew that you would succeed, and I wanted to make sure that you had something special to take back to Nobundo.
Here, <name>, take this flask of pure water. It will ensure that you receive a very powerful water totem.
Farseer Nobundo awaits your return at the Exodar.
Progress
The elements have spoken to me of the great deeds you have accomplished. Come, let us speak.
Completion
You have comported yourself with wisdom beyond your years, <name>. I can sense that the water element is pleased with your actions. It will be my great honor to take the pure water that you bear and combine its essence into your new water totem.
Remember well the lessons of water as you go forward and you will gain an even greater understanding and mastery of the element.
Congratulations! You now have the ability to learn how to create Water Totems, and you have your first Water Totem Spell. Remember that later on, like all other elemental totems, you can only have one out at a time. For a list of all possible Water Totems around, click here. Also, if you want to cast water totems, you'll need the Water Totem in your bag, losing 1 inventory space per Element. It is advisable that you keep all four in your bags, once you have them all.
