Ralam HlaaluI've been stuck on Bahlok for Kyne only knows how long. Anyone have any tips?
It's a difficult fight. The only way to permanently kill him is by using the Eternity Bind Shout before you strike the killing blow. Otherwise his health regenerates. Bahlok has heavy resistance to frost damage and slight resistence to shock damage. Fire is your best bet.
Bahlok begins the fight with Frost Breath and the Silence spell, which prevents you from using magic or Shouting. If you have Ward spells, they can help protect you against Bahlok's lethal frost breath attacks. If you also have Silence, give him some of his own medicine to keep the upper hand.
When Bahlok retreats, make sure to rest up and come at him at full strength. Chests in the left and right rooms can provide help if you're running low on potions.
During the second part of the fight, he'll turn to summoning Ice Wraiths. You can attempt to keep him permanently silenced, or as I like to do, use Fire Breath to deal with the wraiths and inflict massive damage on Bahlok.
In the third phase, Bahlok turns especially evil and switches to the Devour Vitality spell. You'll have to reduce his health while he's trying to steal yours. Similar to the rest of the fight, Wards and Silence spells will work wonders here.
If you're more the warrior type, an alternate approach is to try and stun him with a combination of Unrelenting Force and repeated power attacks. Bahlok doesn't have much stamina, so if successful, this strategy can keep him staggered or prone.
