Shining Balls

Ok so... Umm i am GM on one server for a long time, and today i came online and ported to my favourite place (Sum random island on the map) and i noticed those shiny balls flying around in the air o_o I was wondering what is that, on the minimap i could see a lot of mobs on that island, but normally there were no mobs, just those shining balls. http://dl.dropbox.com/u/19450473/Shiny%20Balls.JPG

Thats the SS

Some1 told me that its the stake with the graphic effect

I was wondering if some1 can answer me few questions

1. Is it rly an invisible stake with a graphic effect?
2. Are there any other stakes with graphic effects ? (Maybe with different balls colours or something like that)
3. Can some1 give me ID / IDs of those?

Thx in advance ;)

Post coordinates... possibly npcgen...

Edit: Actually I'll just get on Deva server since I have the client and pm you

Nvm, I already got the IDs

Thx a lot das7002 <3 xD

An awesome devastation developer called crimson added them from annother wanmei game i believe.
They're not bad at all..l ill try to find where they came from.
