So how does Rikudo Madaras awakening work??

[Aikor]

I heard that he has limbo clones next to him and that they automatically will attack the enemy??Is it true and for how much extent??

From what I saw....It's one of the ability of his awakening, I guess you have to use a jutsu (Limbo border jail) to send them to attack. They could use a senpou raiton jutsu. They'll definitely be a pain the ass.
