Step 1. Sneak to Ironforge, do not engage Gryphon Riders. It will bother you.
Step 2. If you stand "right place", then Muradin Bronzebeard will knock you back to upper area.
Step 3. After you knocked back, then no one will bother you except Alliance players.
Step 4. Spell Priority: Mend Pet - Misdirection - Killcommand.
Step 5. Move your pet to middle of hall not to knock your pet back to upper area where you stand.
If your pet died or knocked back to upper area, then combat will reset.
Time spent: 25min
p.s. I want to post image to show "right place" but I have no idea how to upload image......
