Warlock named Slachz is griefing and abusing warlock spell abilitys in felwood.
We were farming Jadefire Trickster / Betrayers for Felcloth when he started banishing my targets to avoid me from killing them, which also caused mobs to evade and bug out.
I was told to report him for griefing as he also used mind controll (engineering?) to dot me up in an attempt to kill me.
He followed me around, with his friend paladin named Chiby and continued doing this for over an hour.
