Prime Specimen

Prime Specimens are tougher variants of everyday mutants, that can only be lured out with the help of a Prime Specimen Attracting Station. They currently come in four variants:
Strong: 50% DamageBuff, 16 Attack, 10 KnockdownResist
Fast: Haste, Recharge, Defense buffs, among others. Exact magnitudes pending.
Hardy: 5 DamageResist (level scaled), 50% MaxHP
Prickly: Early encounters seen with EnergyDamageReturn, PhysicalDamageReturn, and KnockdownResist. Further information pending.

In order to summon one, you must obtain 12 infection vials of the target creature and a prime specimen primer from the requisition/reward shop. A Prime Specimen Attracting Station must also be set up in the creature's area, though the stations are permanent and reusable. Using the primer will bring up a series of prompts that will lead to the appearance of a Prime.

Prime Specimens will appear at the higher of the area's maximum level or the summoner's level. When defeated, they provide a badge, as well as a boss infection vial.

Boss infection vials can be used to fully infect the user in one go, or give a large boost to an item's XP (30*(level+1), 31*(level+1) for Nanite Controllers). They're also needed to upgrade a power to epic level, and to level up past level 30.
