Ok after reading the another guide i didint agree with somethings, so i decided to start my own guide.
Stats
PURE INT all the way, with bicheon and heuksal skills u have alot of defensive skills, u have kd, knockback,stun,fireshield,fanning spear, ironwall, block from the shield, hp passive
Gear
As a dual build u will have to leave ice at 0, that makes u lose the DEF buffs, so wear protector to give u a nice extra phy defense.
Get a shield with a block of 17+ at least, and a sword and spear with nice stats, unlike other ints, look at the crit of u weapons too, u will use alot of weapon skills, u crit may be low but everything helps, swords and spears have hight crits so its easy to find one and its not too expensive, look too at Magical Attak % AND magical reinforce % both helps u damage.
Skills
This builds uses Bicheon, Heuksal, Light and Fire as skills.
Bicheon:70 Heuksal:70 Fire:80 Light:70, Pacheon:10
Pacheon:
1 lvl in White Hawk and 1 in Passive for some extra Attack Rating.
Bicheon:
*Optional* Chain Sword Attack Series: The chains are always nice to have, they look so good

, but u wont use it at pvp, so get if u want.
Shield Technique Series: a must have skill forget the book 2, max the book 1 and 3, that give u alot of extra phy def for 15 secs.
Hidden Blade Series: The reason to get bicheon, u kd skills, max all books, use only book 2 and 3 at PvP.
Killing Heaven Blade Series:The stabs skills, must have too, max all books, after the enemy is kd use the LAST BOOK FIRST then use the 2nd book.
Shield Protection Series (Passive): Increase the chance of blocking with u shield, max it.
Heuksal
Fanning Spear Series: MAX all books of it, some ppl dont know, but the 2nd book give u extra block, and u can use this skill switch to shield and sword and unlike the one in Bicheon tree the skills dont end if u unequipp u spear, the others books gives u extra magical def for 15 seconds.
Soul Departs Spear Series: MAX all books, this skills gives u a decent damage, but the reason to get it is the stun, u will only use the last book
Ghost Spear Attack Series:The reason to get the Heuksal is this skill, its a instant skill, with knockback, if u crit in this skill its almost a instant nuke, the damage is awesome, the knockback cancel ur enemy skills, the book 2 and 3 are awesome.
Cheolsam Force Series: MAX it no matter what, it gives u 1k of hp, for a int build its alot.
Fire
Fire Force Series: Its u imbue, max it, use it with every single skill
Fire Shield Series: Max it, with this skill and some alchemy on u rings u will be imune to all effects(cold,burn,zombie etc)
Flame Body Series: Get to the lvl 1 of book 3, since the other 2 lvls only increase the duration, this skills give u 7% of phy attack power, u are int yes but u use alot of phy skills, and remeber every liltle bit helps, this skill with the passive gives u 13% more of phy power so get it.
Fire Protection Series: This skills gives u a boost in magic def, max it, u are int and already have high magic def, but why not get more?
Fire Wall Series: MAX IT!, alot of ppl say this skill is useless, forget what they say, fire wall absorvs only magical damage BUT while in it u cant be, frezzed,stunned,kded,knockback, for a STR GLaiver it takes 3 skills to kill the wall, that gives u time to send a nuke and knock he. its a nice skill, if the player go too far from u u can just cancel this skill by pressing the skill in u tool bar.
Flame Wave Series: U main nukes for PvP, the second one is the better nuke in the game for single target, max all the books even the book one, cuz its the faster nuke u can have, in group fights nukes are awesome, but in 1x1 just use the 2nd book, the 3rd book is crap even for grinding.
Flame Devil Force Series: More 6% phy power, why not?
Light
Piercing Force Series: The better buff to any int player, more 16% magical power? HELL YEAH, max it, use it, love it.
Wind Walk Series:Since u wear protector u need every moving speed u can get, max all the books the 2nd one is the one u will use alot in PvP
Lion Shout Series: Max it, its a mini and fast nuke, good to kill other players firewalls, nice for grinding too,
Concetration Series: Max it, more parry ratio means less damage u take, so get it.
Thunderbolt Force Series: The light nuke, very good for grinding, very good in group fights, get it and max it.
Heavens Force Series: More parry ratio, means less damage max it.
The PvP
U will need alot of practice to play with this build, since u will change alot u weapons, so do it while u grind, dont try to use all the skills, start using some nukes and bicheon skills, then put some spear skills in the bar, get used to where u skills and weapons are, in the begining u will get alot of disconnects for network insecurity, but keep training its not hard to get used where u skills are.
This Build works great in 1x1 PvP at lvl 80 and 90.
Remeber, u have alot of tools to stay alive, usually u enemy wont even hurt u if everything works fine, start loading u wall and sending the 2nd book of fire nuke, then right away kd him down, do the 3rd book of stabs followed by the 2nd book(this is important, the burst damage of the 2nd book is greater than the 3rd), when u enemy gets up u still have some time to attack before he starts he skills, so change quickly to u spear, if u crit in any stab move do a Ghost spear mars and that will kill almost everyone with regular gear, or u can do a soul spear soul and followed by the ghost spear mars, that almost kills everyone.
But if the things go wrong? u will almost aways have the shield and sword equipped, the spear is only when u enemy wont hurt u(right after he gets up from a kd, when u are in a wall), if u get kded phantom away right when u get up, if u get stunned too, and start all over again. Always remeber u are a INT player, u cant count with u HP to save u life.

Look at the tactics he use, look how he phantom away if he gets a crit ou gets stunned, strs dont have strong ranged attacks, so phantom give u time to pot while not getting hit, this video shows exaclty how to play with this build
