Hi . i found this script and i want some changes here.

- Only GM can activate this event

- GM can set how many players in this party (3x3) , (4x4) , (5x5), (10x10)

-  the npc will show up for the reward  and The winning party can claim the reward and the party name will be announced in the server

thanks in advance
