Unique Enemies

Tyr-Hadar - Ice Elves:

The unique Ice Elves are technically part of the quests The Plains of Tyr-Hadar and Unexpected Aid, but they will be at their locations whether you accept the quest or not and killing the first Priestess will then initiate the quest. The main reason I included them however is that each will drop an interesting item if you use "disarm". As you can see in the screenshot above the Captains are using the Golden Shield of the Gods. If you disarm the Priestesses they will drop a strange item that you can't actually use and while laying on the ground is called "DO NOT USE". (Thanks to 34y8uhg_345 for bringing that one to our attention at the SIF.) :

They can be found at three locations in the Plains of Tyr-Hadar, the Captains are marked by yellow stars and the Priestesses are marked by purple stars in the mini-map below:
