Avenger (protoss)

The avenger is a variant available in the single-player campaign of StarCraft II: Legacy of the Void.

Overview
When Amon corrupted the Khala, the Daelaam were forced to flee Aiur and sever their nerve cords. Outraged at the loss of their homeworld, some of the Khalai adopted the ways of the dark templar and returned to Aiur to wage a secret war against the zerg. Due to their small numbers, they employed warp technology to save themselves from death on the battlefield so they could fight another day. The Daelaam fleet led by Artanis later made contact with them again and brought them back into the folk as cloaked warriors.

Game Unit
The avenger is the Khalai variant of the dark templar, alongside the Nerazim dark templar and the Tal'darim blood hunter. The avenger is statistically identical to the base dark templar, and have the passive ability emergency recall. Upon an avenger taking fatal damage, they will recall themselves to a dark shrine under the player's control and restore themselves to full shields and health. This makes the avenger much more economical than the other dark templar variants, critical if the player is tight on resources. Their emergency recall has a lengthy cooldown, however, so the player should not deploy them again immediately and let the cooldown wear off.

The player must be sure their dark shrine is protected when using avengers, as if they do not control a dark shrine, or if they do but it is not powered, the avenger's recall will not activate. If the player controls multiple dark shrines, the avenger will recall to whichever is closest to their location.
