create custom mount for cataclysm

Hi, i’m looking for how to do this. All guide i have read is made for 3.3.5a not 4.3.4. I don’t want create custom mount from original mount, it must be new!

As far i know that need create a spell that will summon a creature. I coppied a spell ( example: 49322 ), but i don’t see where i can edit row which will summon creature. Please tell me if you know!

And if you know more specific please tell me

Best Regards!

Try creating an item that runs the .mount command
