Change weapons and armor?

I was told long ago people were able to increase his armor and weapon, fighting 4 people and his life no down, is that possible? someone would be able to create and rent as a bot program by paying a monthly fee?

Increase Armor and Damage is Serversided you Cant change them.

Only thing that you can Change is Speed and Attackspeed

For bots just look in the Hack Section there Are 2-3 nuce working bots
