I had a lowbie mouth off to my high-bie in a totally un-rp'd way, because he knew I couldn't do anything to him.

Sadly, he knew wrong, because I summoned a devil using a certain object and it prevented him from fleeing from the mob he was fighting.

The imm in question didn't seem too concerned that some lowbie had been treating my high-bie like he was a complete wimp. I was told in no uncertain terms that if I did it again...

Personally, I liked creating consequences to actions like that. As a lowbie, I always rp an element of fear/respect for much higher level characters.
