no thats not cheating because the mage stayed out of the way of naggy and always had a pet to back him up.... Naggy would have gotten to him if he never had a pet with him but if you time it just right you will summon a pet as soon as the other dies and sic it on naggy before naggy will target you.
The mage probly just said that because it was the only way to explain it to someone else that wasnt there to witness it
