Cipsoft changed the spawning of the Balloon Cloth. It is now seen after every server save.
An interesting item you can find is Balloon Cloth , but it used to only spawn with the starting of new servers. So we can have one balloon per world.
On the older servers there were two chances to take it - first chance was after update, when Cipsoft has implemented Oramond into the game, second chance was after update with increasing amount of hunting spots on Oramond (Professor Maxxen etc.).
Location of this item is next to the NPC Zeronex.
