@Sol same effect, isn't it? I used to play BDO with a Australian players who played a played the Sorceress class. That guy literally debuffed a boss so much that the damage the boss did barely managed to reduce 2% of our entire HP, status effects and all. That is the advantage with a debuffer. Unlike a buffer who is dependant on the manapool to maintain buffs, a debuffer will cast a one-time manacost spell that persists for a set duration. That is more effective, isn't it?
Don't put me together with those shallow swamp dwellers who enjoy fan service and cheesy harem. I am someone who looks beyond simple harem and comedy and enjoys a good story.
