Quest: Arm the Wards! - Thottbot: World of Warcraft
If you're doing the quest arm the wards and you don't want to do this daily quest the other day too, you can do this:
Simply get 4 Mana Remnants and energize one of the Crystal Wards but don't turn in the quest now.
Now kill more mobs to get another 4 Mana Remnants that you can use tomorrow.
Found this today while doing this quest with a friend. While he needed 2 more i got 4 Mana Remnants for the second time
Have Fun
