Marcus immediately began feeling a wave of unceasing rage coming over him the moment he successfully began possessing Zaila.
The barbed, pitch-black stake that had been lodged into her body was releasing thin dark tendrils that attacked the soul of whatever came in contact with it. Driving them into a fury that painted the entire world as their enemy.
For a moment Marcus almost added his strength to Zaila's rampage, but before he was overcome, he managed to keep a steady head.
He was still experiencing the intense desire to rampage, but thanks to his Still Mind unique skill he was able to resist the effects that would make him lose himself.
'Damn, this thing is way nastier than I was expecting.' Marcus thought as he used his spiritual energy to fight off the tendrils trying to warp his perception.
