How do you buff on fiesta

To buff on fiesta online when you create your character you must select to be a 'cleric'. Then you must level up to level 47 I believe? Then you must buy the skill at the skill master in the town 'Elderine'. Then you put the skill on, and there you go! This buff is not the strongest you can do, if you level up more you can buy the new stronger skills to buff better.
