I loaded an autosave which happened right before the fight actually begins, while Alduin is flying up to me, I bring up the map and fast travel somewhere, I don't think it matters where. I Ftraveled to High H then I Ftraveled back to the Throat of the World. When I arrived I waited for Alduin to finish speaking and I waited for Parthanaax to finish as well. Then I started the battle by equiping dragonrend and the rest was normal. He wasn't invincible anymore!
You can also use console commands to make him become vulnerable again... when the combat is on, open console, select anduin and type disable and then enable. This should work. Should you die during the fight, you need to restart the game in order to make this fix work again
The bug is caused by attacking Alduin before Parthanaax tells you to so the most reliable fix is to reload to before reading the Elder Scroll or if you have no save try fast traveling to and entering High Hrothgar. Seeing as your on PC you could open the console click on Alduin and use the commands disable and then enable to reset him.
is there patch for this because I tried everything and it doesn't work this giltch will acturly break you game if you dont have it installed like many giltch in skyrim say that "you disk is dirty" this only happens if you do some mission or if you continue it will say this and the only way is to restart the game. so please tell me if there is a patch for this for the xbox 360
I climbed the mountain before the fight started, found a nice little spot and just kept hitting him with Dragonrend while shooting him with my excellent ebony bow with fire enchantment, I am Lv 40 and it took me all of 1 min to kill him after getting rid of his invulnerability thanks guys
I fixed it by running down the mountian because I didn't realize I had autosave because I was new to rpg's at the time and after running down the mountian fast traveled to a different destination and then travel back up the moutian and it was fixed
OMG....I tried 4 times, not bothering to 1: go back to an earlier save, or 2: look it up on the internet. So I gave up. Countless hours into my sneak archer, all the best gear, level 41....I deleted all my saves for the charachter. :(...ost fun I ever had in Skyrim was with this character :(......Now I know how to prevent it, it's time to resurect my sneaky kitty and begin anew..Thanks for posting this!
At firts I attacked and did a little dmg because my Skyforge Steel Greatsword does only 44 dmg (I'm in lvl 12 this far with my current account and in lvl 37 on my prmary account). This time I could only fight him down to about 1/10 of his HP but then I got hit by a meteor and died. Then I had to fight "Invincible Alduin" for over 1 hour and I tried to use the "Marked For Death" shout as well and even loading back to the Dwemmer caves. I will try this out now and see if it works for me.
This hasn't worked for me.. it always gets to a certain point with alduins health and he glitches and I can't get it any lower. I get so far then it stops..and I am constantly 're loading the start. So sick of it am going to stop playing altogether soon >:[
Fun new variation. Two Alduin's! One on the ground from the start, the other (with the quest marker) flying around. Had to kill the flying Alduin first to get the "You have not defeated me" speech, and then the one on the ground to complete the quest stage requirements. Ok so technically he slid off the mountain and Shadowmere went running down the mountain path to find him again, but whatever. Quest complete. Flying bombs were still incoming, so fast travel away, then back again, and all was calm and I could talk to Parthanax.
This was after I had to use console commands to complete the video stage!? Get's my vote for the most buggy quest that not even USLEEP has fixed 2018.
