Agility is kinda easy but still....
*Tele home, from here head to the portal labeled agility portal.
What to do:
*You have to go through each door through the mage. You get exp each door you go through. Once you reach the middle you will gain alot of exp and be transported back to the beginning. Heres a trick i learned. Keep clicking on the door and you keep going through it gaining exp relatively fast. Hope this guide helps and good luck
