How to prioritize the use of a skill in bot

[leo162]

Does anyone know how I do I set the bot to prioritize the use of Chain Lightning, on my shaman?

I'm farming cloths because of this need to kill many mobs together thus believe that prioritizing the use of Chain Lightning, it is easier to kill several at once

os: sry for my english

the combat routine handles spell priority

you cant change it like a setting or something
