stoneAC

StoneAC is an anticheat addon I made to work alongside GrimAC. GrimAC is really good at catching movement cheats but it leaves some gaps, especially in combat and inventory stuff. StoneAC covers all of that.

It catches things like autoclickers, killaura, silent aim, and antiknockback on the combat side. For inventory it handles cheats like chestsealers, autoarmor, and autototem. It also has a nuker check, instabreak detection, jesus, and strafe/orbit killaura patterns.

You need GrimAC and PacketEvents installed for it to work. Think of it as the missing piece that makes GrimAC complete.
