The Blood Moon has once again risen over Millennium City, hailing the return of the Undying Lord Takofanes in Champions Online. During the event, players can take on challenges from the previous Blood Moon event to free heroes and battle zombie hordes to earn prizes. But theres also Halloween trick-or-treat bags to be had by talking to trick-or-treat NPCs throughout the city. Once spoken to, the NPC will either hand over a treat bag or turn into a monster and try to kill you. Have fun with that.
The Halloween Blood Moon event is currently underway and will conclude on Monday, November 4, 2013.
