None that can hurt him?

Remember too, that Gandalf's power is still cloaked most of the time. He only unveils his power at truly desperate moments, like when the Nazgul are bearing down on Faramir. And even then, he does no more than drive them off.

Gandalf, were he to completely unveil his power, would have no need of diversions to get Frodo to Mount Doom. The invasion of Mordor would be deadly serious, it would be like the War of Wrath in miniature. Because Gandalf would no longer have any reason to hold back, to only encourage and not command, the War of the Ring would have gone VERY differently.

For these reasons (and those previously mentioned), I am of the solidified opinion that Gandalf was still very "killable" after his return from death. He was just more unlikely to be killed. He had, after all, been enhanced, given more allowance to use his power, and it had taken a Balrog his life to get rid of him the first time. Gandalf would have been beyond the skill of pretty much anyone to kill, but that doesn't mean that he was impossible to kill. He was, after all, still a Maia incarnate.

I wonder though. Does he not remark that "No weapon you have could harm me", or something like that?
