Patch 4.2 added a new legendary weapon for casters called Dragonwrath (link opens in a new window).
To actually get the weapon is no small feat. It requires you to complete an epic quest chain that involves raiding.
We’ll be posting a more involved guide in the future, but this weapon is a BEAST.
It’ll let you turn into a dragon which you can fly around as.
When you deal damage, you have a chance to gain the Wrath of Tarecgosa, duplicating the harmful spell. For dots it will instant cast a direct damage spell of equivalent damage to a single tick of the dot. In theory, each tick of the dot should have a chance to trigger the effect, which means this weapon is going to be a HUGE damage increase.
As you go through the quest line, the weapon evolves into 4 different forms which you can see below.
Whether or not you choose to go after this weapon is entirely up to you, but you will need help from a guild and it will take some time.
As of this post Siiz is the only confirmed player to have completed the quest line.
