Need some help.

[Ratikal]

I am new here, been reading and I just can't seem to comprehend all this information.

Basically, I have two accounts that are linked by RaF. They are mages, with BoA gear. I just want to multibox them as to where they both cast the same spell. Can someone direct me to a link to help me with that? Just getting it set up?

If your software has an FTL option, just drag the spells from the spell book, both get the same spell in the same slot.

If your software does not have automatic FTL, a focus based approach will probably be the best.

You have a PiP hotkey to press, which brings one account to the bigger window.
Within warcraft, on this same keybind, have a macro on both characters which makes the character moving into the big window the focus of both characters.
Do the same on the other PiP switch hotkey, but for the other toon.

Create your follow hotkey, which will be on the same keybind for each toon.
Something like: /follow [target=focus]

All of your dps spells will be this format:
/cast [target=focustarget] Fireball

No matter which toon is in the active window, they are the focus of both targets.
Which means the non-focus toon will follow the focus toon, when you press the follow button.
And both toons will cast at the focus toon's target.
