Starting today, December 13th, and lasting the entire weekend, until December 15th
when recruiting epic units from Specialist beacons in this recruitment rush event,
there is a 20x greater chance of these units being one of the following three:

Nosorog: an Epic Xaoc Chemical Defender
punishes those who attack him,
reflecting some of the damage taken back at those who attack him directly.

Butcher: an Epic Marauder Thermal Attacker
able to hit many enemies in a line for very high damage
and inflict them with inferno as a bonus.

Wisteria: an Epic Gelecek Chemical Attacker
specialized in Damage over Time effects, mainly Corrosion,
and often called the mini-Valerian.

Good luck, Commanders!
