Researcher Pio:
I assume Corrupted Energy is influencing on growlers.
I've kept warch over them and almost sure I'm right.
We need to study Corrupted Energy. That's why you have to kill Frear Growler, Fear Growler Evolved and Fear Growler Robust, gather the energy and bring it to me.
I suppouse you dont't know where to find the creatures, so I'll teleport you to them.
