Player Fck, a Undead Male Mage, was griefing and just being very toxic. Every time I pulled a mob, he would spam poly until I went out of mana and had to run. I figured I would report here so I could attach the screenshots I took.

Didn't have time to record it, so I just screenshotted some of the times he polied my mob.
EDIT: He did this for about 10 minutes.
