If you’re looking for a tool to farm and run champs without aura, the RSL Helper is a great option. This program will run until all of your keys have been used up. After that, you can toggle it on or off as desired. You can also set substat rules to prevent it from running. You can, for example, set rules that dictate when a champ with aura should be sold if you are farming it.
