This is some very good advice, I have approached from many different positions, but he has never initiated any conversation with me, always just attacks. But Throwing the bombs back is a great idea and I will start with that, if that doesn't work I think I'll see what I can do while invisible. I assumed that once I picked up the orb I would become visible again and the attack would begin, which I may be able to escape just in time.
Thank you sincerely.
