Hi im looking for a mod for wow or a addon that let me play on 2 character at a time i do something once and the other mimics

there is no mod to do this, it is possible only by logging onto more than one account and linking multiple keyboards down to a few hotkeys. Everything is done userside.

it is most likely against the WoW TOS, I don't reccomend it.

there is no mod and yes, its against TOS.  Its called Key cloneing.

Nice necro!
