I recently finished my Warlock twink and I have compiled this nice little guide on how I did it. Before I start, you need to realize this is not a 1-70 leveling guide, it's just a guide that will help you twink your warlock up quick, if you need a leveling guide, the best ones are: Joana's 1-70 Horde leveling Guide for horde, and Brian's 1-70 Alliance leveling guide for alliance.

For starters, I was making a Level 19 WSG Lock Twink. Why not a Rogue, Warrior or Hunter you ask? Simply because these are the most over-twinked classes out there and I wanted to experiment with something new. I always finish within the top 3 for HKs with my warlock.

To begin, I started an Undead warlock. Sure, Orc Locks get the +5% Pet Damage bonus...But we really aren't focused on Pets here, seeing as at level 19 all that you will have available is the Imp and Voidwalker...And well...The voidwalker is damn near worthless in 10-19 WSG. WOTF is invaluable, and UD locks also get more INT then orc locks.

For the Talent Spec I went 5/5 Improved Corruption, For the instant cast, 3/3 Improved Imp, Just to give a bit of a boost to Blood Pact, and 2/2 improved drain soul. I've tried going 2/2 Improved lifetap over Improved Drain Soul but due to the lack of "Twink Healers" its pretty worthless...No one likes to heal in BG's anyway.

For my professions I took up Engineering/Mining, simply so I could mine some copper as I leveled to cut down a bit on the gold costs. By level 18 Engineering should be maxed out at 150.

Next is Gear...Estimated Cost for Gear + Enchants...800-1500G. (No I'm not kidding)
For my gear I used the following
Head - Green Tinted Goggles http://www.thottbot.com/?i=1369
Neck - None
Shoulders - Pagan Mantel http://www.thottbot.com/?i=9626
Back- Sentry Cloak +70 Defense Enchant http://www.thottbot.com/?i=3471

Ring- Seal of Sylvanas http://www.thottbot.com/?i=30033

Weapon- Witching Stave +22 Intellect Enchant http://www.thottbot.com/?i=9069
Wand- Skycaller http://www.thottbot.com/?i=42366

Minor Recombobulator Seal of Sylvanas Phew...Now that gear is out of the way its onto Strategy...

Now even though you have all these amazing items they simply wont just win the game for you...After all, your job is support, and HK farming. Don't run into the group of allies full force, Stay in the back to middle of the group, and try to stick with a warrior/rogue at all times. When running into a group hit tab Have CoA and Corruption set to hotkeys 1 and 2 and hit 1...then 2...then hit tab to target another enemy and repeat. Have imp on Aggressive And basically let him do w/e he wants. I really don't bother too much with him. Once they start to drop, throw an Immolation on the warriors/pallies and focus Imp (ctrl + 1) attack on it while wanding or use the infamous lifetap/drainlife combo.
Because you are a lock, and you are a twink, You cant just go out to the barrens and farm soulshards. When you see someone is around 100 HP and dropping fast, quickly cast Drain Soul on them to get a quick shard. Make it into a healthstone, and also keep this on your hotbar. Because you are cursing everything like mad, when they die you get an HK and before long they really begin to snowball upon themselves.

I have a blast with my lock twink, he has better enchants on him then my main does and I think I might have spent far too much on gear...But in the end im having a great time with him. He is known on my server in the 10-19 WSG Bracket well, and feared by many an allie. I hope this guide opened your eyes too more then just the standard...Rogue Assassin Blade Twink, or Hunter Chzer Twinks. To finish this off, if you need more in-depth coverage of battle grounds and PvP tactics, check out Spugnort's PVP guide, there's a small fee for it, but it's well worth it in my opinion.
