Killed this rat on Corinav. Didn't drop anything and no faction hits. Might of split after death. Not sure as he ran around the corner and died to a dot, but a ratling followed after his death.
This guy will split into two when at low hp and stopped moving. The new Teriling is full of life and spring up to attack you while the old one just standing there with low hp like it is supposed to be. Watch out.
