Yeah I have a level 81 character with One Hand buffed by 160% and a Stahlrim sword that does 245 damage after upgrades+Buffs.

Through button mashing, I was able to deplete Miraak's hp bar completely on the first wave of the fight. And when he absorbed the Dragon Soul to replenish himself, his HP didn't fully restore and he became stuck in his Ethereal form.

I had to replay the battle two or three times before I finally did it right and was able to defeat him.

PS3 user, using most recently released console patch.

aye this bug is on all versions of the game ever since DB was released.... and why exactly is this post in the hearthfire forum?

Thought I posted this on the Dragonborn forum...

Weird.

Yes, we know that too much damage causes him to stay stuck like that.

It's probably the biggest complaint in the Dragonborn forums.

happens to all of us i guess.. anyways a similar bug is in the Aetherium Forge questline as well.. in the final dungeon, at the forge, if one changes weapons at any point during the battle itll cause 1 wave of the dwarven spiders not to come out attacking... just so youd know annoying, yes, but nothing we can do bout it unfourtionately

edit: fixed a typo
