However you want your slaves to assist.

The active toon has a target.
You have the slaves assist the active toon, acquiring the same target.

Then hit your IWT hotkey.
If click to move is on, and the toons are out of range, they'll move into range.
Sometimes you'll need two IWT clicks, one to move in and another to open the npc dialogue.

Once you're there, Jamba will have each duplicate the actions of the active toon.




IWT = Interact With Target.
This can be hotkeys but not macro'd.

So you will need to assist for the same target.
And then press the keybind.
