Adds fear, kill adds.
The color combination for the first 3 fragments inserted does not matter. The dragon spawns are based on the color of the 4th fragment inserted. Once a dragon has been defeated, the option to use a fragment of that same color as the 4th insert will go away and you will no longer be able to spawn it again in that same instance.
Ventani: x-x-x-Gold
Nanzata: x-x-x-Red
Tukaarak: x-x-x-Black
Hraashhna: x-x-x-Blue
Drops Mage pants.
You dont get 4 of the same color in one run. Spawn this one with:
Red Gold Blue Black
We just put four of one color in each time and were able to spawn all four. It was pretty straight forward as far as I could tell. Ridiculously easy mobs to kill.
