Clerics, does your basic heals like any other MMORPG out there along with buffs. Based on user preference there are many build types you can go with cleric. Full out Support, Artillery Mechanics, Lure and Bait. (The names I made up, but all different game style I usually play, depending on the situation of the game.) I'm sure there are many more build types out there these are the only ones I can think of with cleric for the moment.

The most common for most clerics in game. All clerics start out with heal, but cant really gain experience until the fight begins. How to gain experience, is just by going out with your allies and build towers until the actual war starts. In the beginning its a bit hard for a cleric to stand in front of line in the war. Sit back let your allies kill the targets while you heal. The best experience is targeting the heal on "Newcomers". Your experience is doubled due to supporting a newcomer, also when you target a lower HP allie the experience is also increased.

When you stack up enough experience for skills for Full out Support You'd need the following skills:
> Sanctuary
> Sacred Armor or Dash
> Resurrect
> Happy Miracle

I'd say these 4 or 5 skills are great for backup support, Sacred Armor for tanking, Ress for fallen allies and more exp, Sanctuary for Groups vs Groups, also good experience. As more skills are used in battle, the more AP is needed to keep a support active. This is where Happy Miracle comes in place. The more members singing with you the higher the AP gauge moves up, also your DEF also increases which is a good deal. Best to use this when you are clear of sight of enemies, unless you have a Sacred Song socket already you can do it in the beginning of the game. (At the cost of building tower time)

> Ones with "★>" before them are harder to get sockets. They most likely come from Premium or Premium+ type gets. For a new comer, stick with the basic buffs till you can get a nice pick.

> AP is always going to run out if your Full out Support You'd need to stack up on some armors and sockets:
> Same Named Buff doesn't stack. Example. Level 1 Attack Up with another Level 1 Attack Up. Do not stack
> Different Names do stack. Example. Level 1 Attack Up with another Level 2 Attack Up. Do stack
> Two Debuffs doesn't stack. Ice Element with a Thunder Element will not stack together as one. It will happen either or.

Weapon Buffs
As a newcomer if you can get your hands on a elemental buff, you are lucky. Im sure its more easier for people with Happy Tickets. But aim for Status effects and stuff that will displace your enemy while you flee to support.

★>Fire Element > Damage Dealing - Recommendation: ★
★>Wind Element > Pushback - Recommendation: ★ ★ ★
★>Ice Element > Freeze Effect - Recommendation: ★ ★ ★ ★
★>Lightning Element > Slows Opponent - Recommendation: ★ ★ ★ ★ ★
★>Stun > Stuns Opponent - Recommendation: ★ ★ ★ ★

Or anything else that seems supportive like, but new newcomers. I would suggest:
>Construction Speed Up > Increases by 15% Whatever level it is (ex. Level 3 - 45% Speed in Building)
>Smash Power Up > Smash, is also good for newcomers pushing people back with weap as well. (I Have this with my warrior, It's funny how they pop like popcorn.) I believe this helps with double right click. Pushes back enemy with shield. More smash the further the enemy goes. (Correct me if im wrong)

Class Specific
> Resurrect+ > To add skill in beginning of game.
> Sanctuary+ > To add skill in beginning of game.
> Heal+ > To get a random 3rd tier skill in beginning of game.
★> Sacred Armor+ > To add skill in beginning of game.
★> Sacred Song+ > To add skill in beginning of game.

Shield Buffs
I Would say anything you can muster up is good already.

Armor Buffs
I would say any debuff you hate the most while playing, get resistance to it. I would recommend these for new comers.
Or anything else that seems supportive like, but new newcomers. I would suggest:

> Any Resistance > Stun, Freeze, any type of resistance is never bad.
> Defense Up > Most Obvious, not recommended but. If it's what you have might as well get it.
★> Mobility Speed Up > Initial Movement speed (Due to issues with game, this might not even matter at the moment)
★> Lightning Resistance > Its annoying might as well. (I hate Lightning)

Helmet Buffs
> AP Recovery Up > The rate of recovery of AP. (Derp explanation - but think of it as the speed of that blue bar filling up)
★> Max AP Up > Cause Sacred Song is more for Mid Game - Not bad having extra AP.

Or anything else that seems supportive like, but new newcomers. I would suggest:
> Experience Up > Higher Experience is never bad. to level up to 5 faster. (Doesnt tally to score though - Thanks TAYLQR)
> Team Skill Experience Up > Higher Experience is never bad. to level up to 5 faster. (Doesnt tally to score though - Thanks TAYLQR)

Accessory Buffs
> Conserve AP > Use less Ability Points for abilities. (Oh god this is very useful)
★> Shorten Cooldown > Straight forward.

Or anything else that seems supportive like, but new newcomers. I would suggest:
> Respawn Speed Up > Just because faster you can get on the floor, faster you can get healing.

This one more for the technical players, who like to, Summon Materials and build. Its a build to actually build (lol). As most of you have already inquired in the Tutorial for Cleric. Clerics can also Summon Materials for backup support for defensive or offensive. There are a few things I like to discuss about this build, which is kind of unique because it ties in with Lure and Bait build, also the Rush Tactic.

> Summon Materials Can distract a NPC to build.
> Summon Materials - When built, destoying them or using them will lure NPCs towards you.

When you stack up enough experience for skills for Artillery Mechanics You'd need the following skills: (This you might have to start out with the Support Build to stack up on EXP.)

> Wall
> Dash
> Summon Materials
> Happy Miracle
> Teleport

This build requires a lot of speed to set up. So the right sockets is needed for this build. For the skills they will prove quite handy for this type of build. For Wall, its priority for NPCs, if they see the wall they will attack it first. (This is more towards Rush Tactic.) For Dash and Happy Miracle, its another I will discuss in Rush Tactic. Teleport, is just there if you and a allie want to escape peril, not bad to have for this build.

Rush Tactic - AI Opening
Greatly effective in co-op due the computers AI. The computers initial move, is heading out to unclaimed towers and claiming them ASAP till there are no towers remaining. Then its a either defend or conquer. The AI second priority is defending their castle from potential threat. or full out rush, usually have one left behind to defend their base, if the one is stuggling thats when the backup occurs.

Rush Tactic - Cracks
The opening is usually they all move together in a army to claim towers. Within that time frame you rush to the castle and begin creating the battering ram. Two important skills for this type of build are Dash and Wall. You could race there if you have Mobility Up, but dash will help you get there a bit faster. The point of this build, is to avoid any contact with any enemy. So look on your mini map make sure no ones following you to make this Rush Tactic a success.

When you stack up enough experience for skills for Rush Tactic You'd need the following skills: (This you might have to start out with the Support Build to stack up on EXP.)

> Wall
> Dash
> Summon Materials

These three are all you need, and if you have backup insurance. (Get a friend who you can get to support and backup you while you build.) So first, set the Battering Ram - Materials. Then on top of the battering ram, put a wall, after the wall start hammering away. Once the wall diminishes, Retreat back, Shield, Run Off, Heal yourself. De-aggro them if you can, run back and hammer again.

Walls Purpose.

> First priority if all the NPC sees is the wall. If targeted from behind, move around the wall, the NPC will attack the wall in priority.
> Good Block for Ballista damage towards you.

Weapon Buffs
As a newcomer if you can get your hands on a construction speed 3, if you are lucky. Im sure its more easier for people with Happy Tickets. But aim for faster builds, and faster movement to get to the other opponents gate.

But for this build you'll need these sockets, but new newcomers. I would suggest:
>Construction Speed Up > Increases by 15% Whatever level it is (ex. Level 3 - 45% Speed in Building)

Class Specific
> Wall+ > Wall is to defend yourself from javelins from the castle. (Temporary DEF against NPCs)
> Dash+ > Of course, to speed you up to get to the gate.
★> Sacred Song+ > Let the opponent have territory advantage. A Good buff for DEF and AP Recovery.

Armor Buffs
I would say any debuff you hate the most while playing, get resistance to it. I would recommend these for new comers.
Or anything else that seems supportive like, but new newcomers. I would suggest:

> Any Resistance > Stun, Freeze, any type of resistance is never bad.
> Defense Up > Most Obvious, not recommended but. If it's what you have might as well get it.
★> Mobility Speed Up > Initial Movement speed, rather then going Dash+ this will really help out.
★> Lightning Resistance > Its annoying might as well. (Lightning is Anti-Speed, Must Have)

Accessory Buffs
> Tactical Power Up > Good Damage with Weapons, except Battering Ram.
★> Shorten Cooldown > Straight forward.
