Now, as you all know, Blizzard's starting a promo to milk the holidays for new subscribers. They're doing this by:
-Linking the trial account and the veteran account by enabling them to summon eachother
-While the trial account and veteran account are grouped together, they earn 3x experience
-After 2 months of subscribing on the trial account, the vet account gets an exclusive zhevra mount.
What does this mean? This means you can "recruit" yourself as a "friend" and double box and level three times faster. And now, if that were not good enough,
For every two levels gained on the trial account, the trial account may grant one level to the veteran account's lower level alt.
What does this mean? That means a level 60 trial, which is completely doable in 10 days, can level up a veteran's account instantly to level 31. Pretty OP, huh?
Well, time for an abridged double boxing guide. Since keyclone costs money and I'm a cheap bastard, I used AutoHotKey (AutoHotkey - Free Mouse and Keyboard Macro Program with Hotkeys and AutoText). You'll need to write your own script, however. http://www.dual-boxing.com/ has a wiki on AutoHotKey scripting.
If you're really lousy with computers, I have a premade script here (Filebeam - Free Fast File Hosting). Password is "dankone". Keep in mind this script is by no means perfect, and you should develop your own. To launch a script, put it in your AHK folder and drag and drop it over your AutoHotKey icon.
EDIT: Macros! I forgot to mention!
Macro 1: Casting macro for my warlock
/petattack
/castsequence reset=combat Immolate, Curse of Agony, Corruption, Shadow Bolt, Shadow Bolt, Shadow Bolt
Macro 2: I set this macro to "1" on my clone clients so we attack the same thing
/assist party1
