In an emergency, Nika can flood her nervous system with hot liquid aggression. Sometimes she does it just for fun.
Nika can use her attacks with any weapon, including a TAG Pistol, and still receive an AP bonus. The AP bonus is uncapped, even if Nika makes more than two attacks in the same turn using a Stim III or Stim IV. Using a Stim III restores only one of her attacks, not both.
