This is uber cool it did work and im sure it still does but it can / will you get you banned if you get caught .
Best if your mage!
1) Open WoW.
2) Open cheat engine and get mountain climb ready (bt not activated)!
3) Goto a gryphon rider and ask to ride the gryphon.
4) quickly switch to cheat engine and activate mountain climb and viola you can control the gryphon anywhere!
If im correct you can use it and attack creeps but you can't get attacked i do not know if this still works but i think it should. I can't test this as my WoW isn't patched yet and i cba to get it right now so HF!
