Vanguard foe

A Vanguard foe is an unofficial term used to describe the enemies that spawn as a result of taking a quest from Lieutenant Langmar. There are three main reasons for grouping them into a single category:
 * 1) These foes only spawn in pre-Searing and only when the relevant quest is active.
 * 2) They do not drop any loot.
 * 3) They are generally unaffected by upgrades that would otherwise affect similar looking foes.
