Scarlet Highlord Daion
Scarlet Highlord Daion is a human that is part of the Scarlet Onslaught army. She can spawn in 3 different locations with other Scarlet Mobs. Her most common spawn location is New Hearthglen, If you plan to farm for just her, I recommend hanging out and farming the mobs in New Hearthglen while you wait for her spawn.
As with all the other rare elites that spawn in Northrend she has a spawn timer of 3 - 6 hours. However, Checking each of the 3 spawn areas every 10 - 15 minutes is the smartest thing to do. You'll never know when she spawns! =D
