Use this setup in same shortcut bar : 1- HydroBlast , 2- HydroBlast, 3- HydroBlast, 4- HydroBlast, 5- HydroBlast, 6- Body To Mind, 7- Self Heal.
All in auto-use of course.
If you still get out of MP, delete 1 HydroBlast
If you get out of HP and dies but MP is OK, add another HydroBlast BEFORE Body To Mind and Self Heal.
Hope it helps you.
