Embra

Description
Embra is a tamable Elite familiar that can be found in the Breach dungeon on heroic difficulty. The player needs to possess a Phantom Wing Mark in order to tame Embra.

"Many mysterious creatures have emerged in the Breach, and Embra is chief among them. Nothing is known of the majestic steed, aside from its remarkable resemblance to Nightmare. There are only theories on how to tame it currently, but they all focus on the Ghost Wing Mark to gain its favor. Clues to this enigmatic mark have been found around Izhora's chest located somewhere in the Breach."

Strategy
Embra is relatively easy to weaken, however it does pack a punch so be cautious.

How to Tame
In order to tame Embra, the player must first obtain a Phantom Wing Mark. This mark comes out of Izhora's Treasure Chests, which are located throughout the Breach dungeon on heroic difficulty. An Izhora's Treasure Chest is opened with an Izhora's Treasure Key, which drops from bosses in the Breach on elite and heroic difficulties. Once the player has a Phantom Wing Mark, they can use it to tame Embra. Embra's health must first be lowered before being able to use the mark to tame it. It is based on chance whether Embra or Masto will spawn. Spawn points are shown under Masto's page.
