Hi guys,

I can't figure out how I can damage Alduin? (First fight, at the top of the mountain after reading the Elder Scroll)
I use the shout to get and keep him at the ground, but whatever I do or cast he won't suffer any damage.

Am I missing something? Can you only kill him when you reached a certain level? (I am level 24)

Thanks in advance for any help and tips.

Use Dragonrend.

Dragonrend him down then hit him a few times, he dies very quickly when he has landed.. Trouble i had was that other damn dragon getting in the way.
