"Specialist" "Underling" "Champion" all need to be listed under the name of the enemy so people are aware of what modifiers they have and for passive trees that involve a certain type. For the longest time I thought those names meant the rarity of a monster, like white blue yellow orange red. It doesn't mean that, each monster falls into a category, the Champion required for bonuses in expeditions and for Headhunter points is for an example, the Exosuit Purifiers, NOT a yellow monster that most people are thinking of.
