Playing a mediocre cleric in Rappelz, you can still requires a bit of attention this guide below, but playing a good one is somewhat complicated. A lot of these things will come naturally to you after enough time, but it's important that you establish these good habits as soon as possible.

Here is the advice on creating a new cleric. Playing a cleric at the very beginning is much like playing any other sort of character. Your goal here is just to get to level(rappelz rupees) 25 or so. After that point, you should only be doing dungeon parties. You can solo at any level to some extent, of course, but other classes are much better at fighting. Don't frustrate yourself by attempting to do it with your cleric, just make an alt to solo with when you don't want to group with people and heal.

Skills:
- Staff Mastery: You can only use a staff for the M.Atk, to boost your heals, and Staff Mastery only boosts the P.Atk mildly, it's worthless. Don't waste your JPs.
- Mace Mastery: You can put 3-4 points into this to get you through levels(Rappelz powerleveling) 1-25 if you like. After that, you'll never use a mace again, if you're a good healer. While if you want to solo later on, put more points into it then.
So, do quests till you're level 25 or so. Focus on raising your heals as much as possible, along with Wizardry Mind and Mental Amplify.
