While there are several different builds for Clerics, there are 2 generalized roles a player can play with a cleric. The roles are Soloer and Healer. We will concentrate on the later one.
The job of a healer is like the is implying to heal. Yet healing in Fiesta isn't as easy as pressing the button for the heal skill every now and then. Timing, Prediction, and the correct Pattern are needed so that u can keep your party alive even in the most dangerous situations.

Basic Concept
The basic Concept i personally use, is the concept of patterns. The concept based on the theory that u have to spam heal. In reality u certainly wont have to spam heal all the time, but in situations where u don't have to, u wont have much to think how to heal, too.
So when we have to spam heal, how can we do anything else? While heal has 2,1sec cooldown it takes only fraction of that to be cast. So we are left with about 1,8sec where we are not doing anything. We can use that time to look who to heal next and/or to cast another skill!
So what we can do now is casting Pattern of 2. For example: [Heal, Regenerate]. The Trick is to think about the 2 skills(or Pattern) as 1 action. That will help u to have enough concentration left to think about the next Pattern to use!
While in the beginning u shouldn't have more then 1 target while using a pattern, u can always try later to target more 1 person while using a pattern.
Like [Heal:Tanker, Regenerate: DD]
Skill Descriptions
How to use the Cleric Skill is always a point where different philosophies meet. So don't expect my interpretation to be the last word in that matter.
Heal
Heal is the most important and most used Skill we clerics have.
As a Healer there is no discussion about reducing its cooldown and sp-costs as much and as soon as possible.
Invincible
Invincible is in my eyes a not very useful skill, but i helped me sometimes to keep someone alive.
I have seen a lot of healers using Invincible right after the puller returned with a train. I personally never do that, unless i fear the puller cant take on his own train.
I would advise to use Invincible as less as possible, so u have it ready all the time. After all it is a great help when a mage succeeded in taking aggro of the whole train. But don't over estimate the skill, heal is far more powerful over time.
I wouldn't put a single skill point into it.
Cure
There isn't much to be said about the skill. Except maybe that it is fast to cast. Just use it when needed!
No skill points needed.
Restore
Is a handy skill i use often. It isn't powerful, but it helps with little dmg. After all there are a lot of people who forget there hp completely and would die on a single enemy. Just use Restore on them, and they are healed all the time

.
It also helps in tight situations where your heal is just not enough.
I wouldn't put skill points here, too
Rejuvenate
A nice but dangerous skill, that helps a healer to become its worst incarnation, the Clanker. Rejuvenate is a more powerful version of the heal, that only takes a little more time to cast. Yes, u can start casting new skills right in the middle of that skill. Just look at the red bar. Its actually fits perfectly between 2 heals.
Yet there is a big downside to that skill. It creates a lot of aggro, so even if u are tempted to use that skill all the time on the tanker, don't do it. But u can use that to your advantage too. For example u can use Rejuvenate on mages, with luck the monster will stop attacking the mage and are coming after u now.
reducing its cool down cant hurt.
Common Patterns
here i will write some of my own patterns, and the situations i use them in.
[<nothing>]
If there is nothing to do, just do that: nothing
[Heal, <nothing>]
Basic Pattern and the foundation of most of the following patterns
[Heal, Restore]
Increases heal rate
[Heal, Rejuvenate]
Big heal, for tight situations
[Invincible, Restore]
Best for Archers and Mages with to much trouble at there feet.
[Invincible, Rejuvenate]
Same as above, but more aggro
[Heal, Invincible]
If someone is below 25%
[Heal:Tanker, Restore: DD]
Good combination when the DD got aggro for a few mobs.
[Heal: DD, Rejuvenate: Tanker]
in situations where too many mobs were pulled, and DD get a lot of aggro
Important: Watch your own HP
These are the most common patterns i use. But they can combined if needed. Like if u want to use [Invincible, Restore], but u cant stop healing so u combine the pattern it with the basic [Heal, <nothing>] pattern into: [Heal, Invincible] [Heal, Restore]
Tips
Buffs
We all how much it is a pain it is to watch over your own and the parties buffs. To make thinks more easier buff and rebuff them always at the same time. That way u only have to watch 1 timer.
Getting Attacked
When u get attacked don't run around! U are a cleric and with that the 2nd best tanker in fiesta, and the most visual armored too. So act like it. When u get attacked
move a little bit to outside, so that your mates can see that u are getting attacked, alternatively navigate them into the next mock of the tanker.
Also in dangerous situations, don't heal yourself. It will fixate the monster on u even more. Use stones and pots, and use your heal to keep the rest alive.
Grinding
We all know how hard it is to grind several hours continuously. So here is some stuff that helps.
-Don't level with high risk all the time.
-Don't look at the xp, it wont come faster if u look at it.
-Relax yourself with some music or something like that. I use a Harry Potter audiobook, or more relaxed metal. I can't grind while listing to "Six Feet Under" lol.
-Talking always helps to kill some time. But don't forget that chat deaths are very common!
The best result u can get is when u are wondering were the 50% exp are coming from.
