Phoenix Tail Feather

The Phoenix tail feather is a plot item in Dragon Age: Inquisition.

Acquisition
Random loot of phoenixes in the Western Approach. It can be obtained before the related quest How to Lure a Dragon is acquired.

After Frederic gives the quest to the Inquisitor, three possible locations are marked on the map, where phoenixes may be encountered. The nearest and most likely first point, the Inquisitor will arrive at, is the border of the Death Drink Springs, where phoenixes leave this gas-poisoned region and wander into the Giant's Staircase. The other two locations are further to the north-northwest.

As a plot item the tail feather doesn't appear in the player's inventory.
