[Artica has been Marked for Death by the Slayer.]
[All attacks and spells against Artica will deal 25% more damage for the duration. This effect doubles for the Slayer.]
The skill used by Nightshade is something that is incredibly useful and broken. This is the perks of the job class called Slayer as his job class is made to kill not just monsters but any person. The fact that it could increase the damage of any source by 25% and double that for the Slayer is quite something.
The duration of the Marked for Death skill is supposed to be twenty minutes, but it is halved due to the one being marked considered as a mythical tier NPC. As soon as all the players received the notification about the status of their opponent, they suddenly went from scared bunny to hungry tiger.
