thought it would be good to put it in the guide section.. not one of those cookie cutter builds
The Healer Build
This is the healer, the pure talking and walking flesh of sanctuary. Just don’t be fooled be the heals, this build can pack a punch with the cold series to freeze you in your tracks and the bow’s hawk to crush you. Of course if you get through all that I doubt you’ll do much damage especially with crystal wall in effect.
(Credit to DSX for help with this build)
Build Name:
Saint, Messiah, or The Pure Cold Heart
Stats:
Pure INT (I wouldn’t suggest hybrid for this build)
Gear:
Weapon – Bow (You can go Sword + Shield if you want to be a Holy Knight
but realize that crystal wall will be kinda useless)
Clothes – Garment (Armor for some situations)
Skills:
Force Mastery
Heal – Max the whole series
(This is what makes you the savior and self heal is really unnecessary when you have this)
Soul Rebirth – Max the whole series
(Healer build is just not complete without the ability to resurrect)
Harmony Therapy – Max the whole series
(You’ll want this maxed for your parties or anything with a group and always helps when soloing)
Vital Spot muscle – Max the whole series
(Now this is where we get to skills that are more offensive to the monster and will help out a lot, as well as vital spirit in making the monster weaker)
Force Increasing – Max
Extra Mp – lvl10: 102, lvl20: 197, lvl30: 329, lvl40: 509
(As a pure INT character you’ll still want this maxed, it only helps)
Ice Mastery
Ice River Force – Max the whole series
(This is your main skill for fighting)
Weak Guard – Max the whole series
(More defense? Yes please)
Crystal Wall – Max the whole series
(With high MP, using crystal wall will take a while before you die)
Frost Nova Wind – Max the whole series
(For sticky situations)
Snow Storm-Ice Shot - Max Book 1 (Max whole series is optional)
(This is good to have as an extra attack, second book is good if you go all the way..
AOE 
)
Cold Armor – Max the whole series
(Can you say, more DEF please?)
Pacheon Mastery
Anti Devil bow – Max the whole series
(Good to have as a basic skill to go with your imbue)
Black Hawk Summon – Max just this book
(You’ll want this as a sidekick for extra power)
Strong Bow – Max Whole Series
(It's usually a main attack for most)
Mind Concentration – Max the whole series
Attack Ratio – lvl10: 9, lvl20: 13, lvl30: 17, lvl40: 21
(It’s nice to get the extra attack)
As a healer you’ll still want some good attacks and with this skill list you can probably already think of the combo.
Comments:
Good support in both defense and offense. You’ll have the full support anyone would want and a good freeze to stop things in your way, but if it fails you always have crystal wall for protection. This build in a distance is always on the supportive healing, nuking (Strong bow), freezing and decreasing people’s stats. When it came to offensive you have plenty of your cold imbue + devil bow combo, which would have a good chance of slowing them down, plus your bird would come in for an extra hit. If they ever reached you, the crystal wall would stall them.
Overall Effectiveness:
#1 Healer/Support
Good in groups
Strong defensive
Strong INT good on magic defense and hardly run out of mp
Nice simple combo for slowing and killing the enemy
Job Preference:
I would suggest any job would want you, but as a trader if you wore Armor for the trade runs you would be highly useful in keeping your team alive as well as yourself. You could piss people off as a hunter though.
Here is a picture of a similar build (This time it’s from ISRO, not the Asian servers).

cept this is hybrid or more strength. full INT should be better though
