Statssimple, put all your character points into INT. If you don't know why, I should slap you
ArmorArmor-(recommended when grinding or pvp) good physical defence, lacks magical defence. slows you down in running speed
Protector-(recommended when pvp or grinding) has both physical and magical defence but not great in both. has a small mp bonus, gives faster running speed then armor, less than garment
Garment-(recommended when in caves when fighting nachals) has good magical defence, lacks physical defence. gives a good mp bonus, you run faster than protector and armor
I am wearing armor right now, then I am switching over to garment or protector for 7th degree. then im switching back to armor.
WeaponYou are either going to use a sword + shield or spear.
DO NOT I repeat
DO NOT use bow when you are making a nuker (except when you are sp farming in the bandit den, but thats another story). Bow nukers just drive me crazy.

The bow is a ranged weapon and the only ranged attack you need is your nuke and the bow is neither a STR or a INT weapon
The two weapon choices has its pros and cons.
Spear- better for lvling, does more damage then the sword but, you take more damage. Passive gives extra health
Sword- better for pvp, you take on less damage but, you deal less damage. Passive gives more blocking ratio
I say, when you are in the higher lvls, you are eventually gonna get the best gear so staying spear would be a good option. But, if you are gonna get good gear and go sword, it doesnt really matter. If you cant afford good gear, go sword and shield. Sword and Shield is what most nukers choose. But, do not get both sword and spear, only choose one.
Which leads me to my next point.
Masteries and SkillsLets start off with masteries.when you get the the 90-100 cap, your gonna have to choose two-three masteries and delvling one. I would choose not to get cold. Plus, lvling cold anything above 60 is a waste of sp. So choosing lightning, fire and weapon tree, it should look like this at the final cap(assuming the final cap is 140)
weapon tree-90
light-70
fire-140
you could play around with that to your liking.
another thing, your lightning mastery is just your sub, you are getting it for the buffs. So, you would lvl your mastery tree higher then your lightning because for every mastery lvl you put into your weapon tree, makes your weapon 1% stronger. For example, a person with a weapon tree at 60 and another person at 70. The person with 70 in his weapon tree, his weapon will be 10% stronger than the person with his at 60(assuming they have about equal weapons)
also, in ksro many nukers at the 90 cap have just lightning and the weapon tree. And, here is a little secret not many ppl know(credit to Fly) when you use all 3 lion shouts one after the other. It does the same dmg as a nuke but, it casts faster. So, you would still be ok if you just went lightning and weapon tree. The masteries should look like this.
Weapon- 140
Lightning- 140
you can do anything you want with the extra 20 mastery points you have.
Now the skills.Your main skills should be fire and light or just light if you choose to.

Grinding and Sp FarmingDo quests till lvl 35-45, then you will have to get a gold ticket because you will lvl really slow. When you are finished grinding your gold ticket for the day, go ahead and do your quests if you wish.
You will basically grind on mobs the highest lvl mobs you can 1 or 2 hit. (after you get your nukes at lvl 30).
When sp farming you will want to grind on green mobs (when sp farming at the bandit den at 16). I farmed 10k sp there. Then I closed my gap and started to lvl. When you reach the lvl cap, all you are doing is finding new gear, job runs, and sp farming. So, I will sp farm then. When you get there, you will want to farm on monsters you can 1 hit or nuke and lion shout.
I hope this guide helped you make your nuker. I do not claim to know everything but this is what I have by observation and data collection. Please feel free to correct or add anything by posting a reply.
this seems better in my opinon becasue at cap 100 bicheon get new chains with fear and some other stuff.
140 lightning is a must for putting out high damage with nukes and mag buff.
60 ice for 40% snow.
