[CEAA-Script] Room_Mode_Change_Item

This packet is used by S4 to set the snowball bomber and the default skill for this gamemode called snowball fight.
S4 sends an empty version of it where it disable the mode if you join any room.
So just edit it and you can play with weapons and skill which are not in your inventory.

this screen is to show you how it looks ingame.
Perfect for private servers (at least snowball patch) to create rooms with rules
