Best practices for multiboxing World of Warcraft (and Classic WoW).
How to launch second WoW client with different settings or account.
1. Open the folder where WoW client is installed.
2. Find the file "Config.wtf" (should be in subfolder "_retail_\WTF\" or "_classic_\WTF").
3. Copy it as "Config-minion.wtf".
1. Find WoW executable file (should be "_retail_\Wow.exe" or "_classic_\WowClassic.exe").
2. Create a shortcut for it.
3. Open shortcut properties.
4. Find line edit named "Target:".
5. Add a space and then " -config Config-minion.wtf" after executable name.
6. Save properties and launch this shortcut.
From now on, WoW will separate all settings made in this client from your main client. Also, you can use a different e-mail to log in.
How to send a minion to loot a dead target.
Just right click on that target. After a few moments minion will run and loot
(assuming you did all required steps in setup and have Right-Click=>InteractWithTarget feature on).
Ensure that your selection was correct, or minion will run to the wrong or previous target instead.
How to ask a minion to loot in-game object like node or chest.
See Gathering Guide for easy ways of gathering.
How to stop a minion.
Just press the "back" movement key (usually it is 'S' or down arrow).
Also, you can press both left and right mouse buttons. Minion will run forward but stops when you release buttons.
How to turn a minion to a target.
Press the Interact-With-Target key, then press the stop key.
Since F11 is uneasy for pressing, you can make additional keybind for Interact-With-Target.
How to cast AoE spell.
Variant 1. Make cursor-cast macro /cast [@cursor] Your-AoE-Spell-Name-like-Starfall-or-Blizzard
and use it instead of the spell itself.
Variant 2. To land a spell, just broadcast mouse click by double-click or click with any modifier.
How to understand what minion is doing (or why not doing).
Go to minion's "Settings -> Sound" and enable "Sound in background". Then try to cast and just listen to what the minion tells.
How to accept/finish quests on minion?
Install EMA addon. It will automatically handle quests on a minion.
How to ignore some instance(s) of WoW.
There is no easy way to point which WoW window should be ignored.
However, you can open "Game Menu -> Key Bindings" menu in the WoW instance you want to ignore. When this menu is open, the instance will ignore any keypresses.
Best hotkey for primary damage spell.
I use "mouse wheel scroll down" for the primary damage spell (or macro). It makes damaging like browsing a page.
"Mouse wheel scroll up" is used for opening spell/macro, and "wheel (3rd) button" as second damage spell/macro.
These events are all broadcasted by default.
