Introduced in: Sins of the Fathers
Located north of Sanamar at 72.8N 60.7W, the Monster Fight Bookie will take 5 MMD and give you a Monster Fight Ticket. Once an hour eight combantants will spawn in the cage, give your ticket to the one you thing will win. If your pick is the last monster standing at the end of the free-for-all battle, give the stub to the Bookie for your reward.
Monster Fight Bookie tells you, "I take 5 MMDs to buy a ticket. Bring winning tickets to me before the next fight and I'll reward you with a Grand Casino Key."
Eight fighters enter. Only one fighter will make it out alive! Prepare for an all out, no holds bar, brawl!
Let's get ready to rumble!
