By the way, the no cd hack also come with a feature which is "semi item vac"
But first i want to explain about the No CD hack first.
Whenever you logging the packet, it logs the Coordinate of your character together with your full map skill.
So, when you SEND the packet, the Full Map skill will cast at the entire coordinate.
In other words, your character's soul will teleport to the location where you logged the packet and cast Full Map Skill , you killed the mob and your pet take the Loots. Because the action is as fast as THE FLASH
therefore it looks like Item Vacuum hack. (it unlike PC Ver Item vacuum it utilize teleport then the pet take the loot so it)
Let say the Map has 3 platforms Top lane, Middle lane & Bottom Lane, i logged the Packet at each different Platform. When you start to send all the packets at the same time. your character will stay still but your "soul" teleport to each platform and cast the Full Map Skill. So, you can just find a safe spot to afk, but beware of Lie Detector Test.
