Adventure Quest Onehit Cheat (still works)
The age old one hit kill cheat for this game still works,it just seems to bug out when u put it in the adress bar sometimes,to counter that it is quite easy.For this u need to be using Google Chrome as I don't think u can do it on other browsers (AFAIK).
1.So simply start up ur game,start up a battle (does not matter which monster or event)
2.Right click the page but not inside the game window -> click console and copy paste this line ;javascript:document.embeds[0].SetVariable("_root.monster.intHP", 0) , after u have done that remove SetVariable and retype it (SetVariable).After that copy the new javascript:document.embeds[0].SetVariable("_root.monster.intHP", 0) that u pretty much just removed and retyped the same word.Wait for the fight to give u ur turn and press enter in the console with that line and ur enemy has 0 hp.This is not patched,any problems post below unless concerning other browsers as I have no idea.

Works in Mozilla Firefox. No need to edit.
