Auto Dungeon Runner Bot/Plugin

I seen many players botting in popular popping servers, it usually goes as follows:

1. stand in bottom left of nexus until a dungeon is popped
2. run towards dungeon portal and enter
3. afk until boss is dead and chest spawns
4. autoaim chest and autoloot drops
5. wait 30 seconds for pops inside the dungeon otherwise nexus
6. repeat

Is this bot/krelay plugin available anywhere?

Yes it's called like nexusdungeons or something like that I saw it somewhere on github not sure if owner took it down or what.

Yes there are bots like this. (I have one)
No I dont believe they are public
And if somehow you get one, you would need to edit the code in the .dll. There is "whitelist" in the .dll that only allows your username to run it. (It's krelay plugin btw)
