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
i think this would be a cool build to try.. it would be really good in war and big trade runs..
Ice\Force Bow. i'll give it a go when i power level 2 chars later
plus i would like to know how much dmg that force skill does.
