Well i came up with the idea while playing WoW and well its the noobs fault that they didnt listen to the warnings and run away from it. its not like vines because you can run from it and not die and its not really a random because it would come every 2 hours or so. there would be new high lvl npc guards that are only aggresive to this new monster and it would drop like a new rare weapon like a sword made of flame, a bow made of dragon bones, or a staff made of flaming demon bones and the random part would be there would be three different types of monsters there would be a mage, a warrior, and a range. also think ti would remove a lot of noobieness from the game becausae people would have to work together to defend themselves.
