Hey guys I'm Rigour and im going to show you how to stun made easy. Stunning is 108k xp/hr (1200 cast an hour * 90 xp per a cast). With the recent update of the soul rune altar, soul runes have dropped to making this a cheaper and faster method than alching.
First off you will need a -65 magic and a mudd stuff. Heres an example of a setup.

After you get a setup thats -65 magic bonus you will need to set your client to the expandable ratio by going to options (the wrench) and click the setting thats highlighted below.

Now time to setup your F key for the magic tab you would like to open and close with. For an example mine is f4

Now lastly setup sticky keys by hitting shift key 5 times resulting and clicking ok. this will allow you to click with the number pad 5 key.
Your ready to stun splash now. Go to magic tab and select the stun spell. Stun the npc first to get it aggressive to you and align it under the stun spell like so.

Now press your F key that you assigned the magic tab to and it should bring it away like so leaving you with the stun option over the npc of your choice.
Hit the numpad 5 key and it should click resulting in casting the spell. After casting the spell bring the magic tab back up with your F key and repeat.
Thank you guys and if yall need any questions dont be afraid to ask and ill do my best that i can to answer. Yours truly Rigour.
