Most people do not suggest for your first character to be nuker, because of a number of reasons:
1) Nuker Build is delicate, the difference between a good PvPer and Grinder, and a nuker that can't kill greens is just a matter of a few points.
2) Nukers need a lot of money in the beginning. For manuals, speed clothes, etc.
3) Nukers grind on reds. Which means more xp, less mobs, and so the chance of drops, like BE and weapons, is less.
This guide is designed to be help you get through, economically, with a nuker as your first character.
*My first character on Bardo was a nuker*
For building your nuker, check out Tiamat's nuker guide:

From OC1 - RL1, grind on Tigers in Shaolin. I know it is boring, but it's the best spot to train, as it is a safe spot, and you do not need to run around, hence you don't need any speed clothes. At this point you probably have some money, so go ahead and buy a bracer, though no need to buy any manuals, unless you find a bargain.
Train your buffs at double xp, and everything will be fine. I got my Slow nuke, your primary nuke, to cheng 10 at OC9, so you should be close to that.
From RL1 +, grind on Vanguard Devas in Nanchang. They are really really slow, and they drop Mansion passes, which sell up to 800k. Sell the passes, until you have enough money, and SAVE THE REST.
When you get to SM+, you probably don't need this guide anymore.
Your most wanted List:
1) Advanced Med and Steps
2) Decent Bracers, preferably crit bracers
3) 150 Chi Kung Damage WB.
Alright, that's a wrap. If you have any questions, feel free to ask =).
