Ok It's kind a stupid but it wokrs in 90.99 % servers were items can be droped ;D
You will need L2phx and find some server :)
I do this with mp potions, you can do this with whatever you have (but u must have it alot atleast 10k)
Login into server drop for example 1 adena(i am doing with mp potions because i have them the most) and get code "requestdropitem":
Copy code and paste to l2phx "Send packets"
The options shuold be like this:
and press "send every"
You shuold start droping items...and people will start say ;D :
You can do with one pile but i do whit 6, bigger lag and server crashes..
P.S. dont look at piles you are droping it makes much lag better look other side ;D ;D
Good luck :)
BTW drop items near gm shops, respawn places, were is much ppl...
