You teleport to Agility area, and the first obstical, the log crossing, you can spam click it when your in the middle of the log and you will glitch and you will keep gaining exp... Helpful if fixed, make game funner if you actually have to work for a 99...
To be honest I did abuse this bug for a few minutes but anyone could easily set up an auto clicker and get 99 agility...
Many Thanks
