Alright on i believe antrix im not sure what other server but.
If your a warlock and you run away to the point where as the mob stops chasing and start to go back turn around and cast ShadowFury if they arent immune to stun they will stop runnigna dn just sit there they evade all melee attacks but casted attacks still hit and they wont fight back. you can still loot after words you get same exp and everything
im not sure if this is possible will other classes
HAVE FUN
