Combo botting with facc knights

[Iohannes]

I would like to make some epic traps with 8 free accounts knights surrounding the target.
However, I don't really know how I would do this with either War.net or Basic war tools since they require you to use either a rune or a spell, I believe.

Edit: I want the combo leader to work so they all just target the same guy as the combo leader in simpler words.

Thanks in advance.
