anti-pvp /cast macro

[Voxxel]

Hello,

I'm from a PvE realm, and looking for a way to cast a damaging ability that needs to hit mobs only (not players) to avoid becoming pvp-flagged accidentally.

I hope I can do it with a macro, and if so, I finally can spam a damaging ability (before the spawn) to tap some specific mobs without having feared of some enemy players turn me pvp-flagged. They often turn their PvP on and walk in range to intercept some side damage and turn me PvP-flagged aswell. I want to avoid this.

I found some interesting macros around the net but not that specific I want to use for the above. I was thinking of a "/cast [conditionals] MyTappingSpell " style macro but I couldn't found the proper conditionals to make it damage the mobs but not the players.

If that's just not possible, lets say I have a mob named "Amob" I want to spam-tag when it spawns. can I do this by avoiding to hit enemy players?

Something like "/cast [target=Amob] MySpell" -- but that doesn't seem to work.

Thank you for any help!
