Patch Available - KMST 1.2.456

[MENTION=1152]byakugan[/MENTION]; What you're describing sounds like certain event bosses we've had. Most notably the anniversary cake boss of old, that would spawn in a town and take a lot of strong people to kill - and the fastest looters got the spoils.
We also get that when we have a GM event where they summon major bosses in town.
(Or a hacker event when they summon major bosses in town Too lazy to dig up ShinkuDragon;'s tales of trying to kill Empress with a bunch of random newbies, but they were entertaining.)

Free loot works very poorly in Maple. If you live in California and have a pet, everything is yours. If you live elsewhere or don't have a looting pet, good luck getting anything.

only to get nothing in the end. blergh agreeing with everything here. your best hope is having the pet loot the stuff that falls on top of you
