Or use Marked for Death on him. It makes it ridiculasly easy. After it took its effect I one hit him each time he regenerated his health. Kind of sad actually. (Note my sword does 170 dmg but if you hit him with MFD twice it should do the trick.)
Im level 54 and he kills me easily by glitching my potions out of my inventory and kills me then when I respawn at my house they aren’t glitched....(what I mean by glitched potions=he made them not usable and then I die)
Although I'd imagine you'd need to perform the shout at least 3 times since Miraak teleports and becomes ethereal when he runs out of health. When he does that, I'd think that he would be 'unmarked', and would no longer be targeted by lightning strikes.
So it's a good idea to have the blessing of Talos as well as the amulet to have shouts recharge faster.
