Dispel Magic will make all the difference when fighting Doomsayer. I don't think I would've vanquished him without it! It'll dispel his blur and his flame blade both. With his fists alone, his damage is minimized and he is never able to kill, as fists only knock someone out. Though it'll only come to that if your party is still too green to kill him before he manages that.

Ranged weapons seem universally ineffective. Fire, ice, acid and magic damage spells will work, though he has high save throws, at least whilst "blurry." Lightning will heal him, as he has over 100% lightning resistance.

To disengage, you'll need a distraction and the best one is either summoning creatures or summoning a bear from around the area. Web will work well enough, though he has high saving throws and won't give up the chase despite being out of sight, you'd probably have to flee the zone and return, to disengage combat.

TL;DR: Dispel Magic.
