Goal :Building a 2:1 Hybrid int sword and shield nuker. Based on DEFENCE and AOE. Kill fast, much, and receive less dmg as possible.
Skills :
Bicheon
Hidden Blade Series
Very usefull in PvP and PvE. With a bit of luck you can knockdown your enemy. You should max it, so the utilisation of this skill with stab is ownage.
Killing Heaven Blade Series
As the Hidden Blade Series, it is very usefull, because you can hit your enemy while he cant
.The third book is a double stab, I think it is worth lvling this skill to get it, as it generally kill your enemy in pvp. In wars, if 2 sworder/blader use it at same time, the target has no chance.
Sword Dance Series
Optional, it can be good for the AOE (Area Of Effect). You can hit 3 enemis with that skill.
Shield Protection Series (Passive)
You are a sword & shield nuker! your shield is your best defence! So get a shield with a nice block ratio (more than 15 imo) and max the passive
P.S: No, i dont use chains series
Cold
Frost Guard Series
It temporarily increase your physical defence, it is very usefull imo, so get the third book and max it.
Snow Storm Series
Get the first book at lvl 30. The first book is pretty weak, but you'll need it to get the second book. That second book is very usefull for the aoe it procurs, and btw it looks very nice haha
So get the first book at leave it at lvl 1, at lvl 50 get the second book.
Cold Armor Series (Passive)
If you use it with frost guard series it seriously reduce the physical damage, so try to lvl it as much as you can.
Light
Piercing Force Series
You NEED this buff. It increase your magical damage, and you are a nuker, so you need to make as much magical damage as possible, so max this.
Wind Walk Series
Grass Walk is a must, get it, max it, and then get Grass-Walk Speed. It makes you run faster, so it means you can go faster from a mob to another, and you can also catch your enemies while jobbing, or run away from them
Ghost Walk Phantom makes you teleport from where you are to where your mouse is pointing, it is also very usefull, so get that book and lvl it if you need.
Lion Shout Series
It is a sort of quick nuke. Get the first book, it is usefull to finish a mob, or to kill low lvl thieves while jobbing.Get the second and third book if you want to go pure int, but i dont think it is very usefull as 2:1 hybrid.
Concentration Series
As i said for the shield, you need good defence, and this skill increase your parry ratio, so get at least the second book maxed.
Thunderbolt Force Series
A great nuke. Lvl up a bit the first book when you are between 35-50 so u still make much damage, then get second book
Heaven's Force Series (Passive)
Max it, same reason as shield and concentration series ^^
P.S: As this build is based on AOE, you can also get the lightining imbue.
Fire
Fire Force Series
This is my imbue, maxxed. Makes much damage and burns the enemy (kekeke)
Fire Shield Series
It is very usefull because it decrease the damage received when burned. You can beimmune to ice if you max it. If you plan to PvP much, max it, if not, get only what is usefull for you vs mobs.
Flame Body Series
You are INT, and this increase PHYSICAL damage, so get the first and second book, third is ok but you're dealing with magical dmg.
Fire Protection Series
Everything that can give you more defence is good, s you dont have much HP, so max it if possible, but try to get atleast 3rd book.
Flame Wave Series
Get first book, second if you need, and third is great for the AOE!!!
Flame Devil Force Series (Passive)
Imo it is optional, because you already have the flame body series, but you can get the passive if you need/want
Force
Force Increasing Series (Passive)
Gives nice amount of MP, optional though.
P.S: If you are a crazy harcore farmer, and you're gonna sp farm 150/200K, get the heuksal passive WITH Force passive.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
SP FARMING
Well you will need a large amount of SP, so if you can, SP farm at the den when you are lvl 16. IMO the Den is the BEST place. When you are higher lvls, it sux to get a 9lvl gap if you dont use GT. You can also lvl up with 5/6 gap but be carefull not getting stuck in the 4X/5X.
Gear
I recommend Armor or Protector. Protector is a bit better because of magical dmg reduce, so mobs like taoists will make a bit less magical dmg.
Alchemy
If you can get +3int and +3str on you gear it would be great!
For pure ints, only add str, because you alredy make much dmg.
Stamina Stones will add HP to your gear, it is usefull if you feel like you dont have enough HP!
Penetration Stones will reduce the enemy's chance to crit you, as you don't have much HP, it is better
Dont try to add crit stones, because nukes dont crit. O.o
Try to have the highest block ratio, it is always usefull.
Also try to increase your parry ratio.
CONCLUSION
This build is based on defence, your best defence is your shield with its block ratio, and then your concentration buff that increase parry ratio.
You also have much AOE attack (nukes, 2nd book of ice, all books of light and 3rd book of fire).
Be VERY carefull with Aoe!! dont get mobbed lol, even if your block ratio and your KD can save your life, dont try to kill 20 mobs at same time
The advantage with 2:1 hybrid int based on defence is that you can tank because you get less dmg!
Btw, try to select the skills you want by advance, and use this sp calculator to determinate how much you need exactly.
