Defeating Karstaag in Legendary difficulty (Skyrim) without any cheats / exploited gear.
Karstaag is a powerful foe and can prove to be quite a challenge, making him one of the hardest bosses in the game. He attacks much like a regular Frost Giant, using his club, fists and stomp attack, however these inflict much greater damage. His stomp attack is so strong that it can throw the Dragonborn across the room, much like an Unrelenting Force shout.
He also has a permanent frost cloak with a large radius that inflicts frost damage, the severity of which is dependent upon game difficulty. Occasionally during Karstaag's stomp attack, a blizzard will begin to swirl in the courtyard, inflicting additional damage to health and stamina over time, which itself can be fatal. Because of this, some form of frost or magic resistance is useful, especially as stamina can be depleted within seconds.
Karstaag is completely immune to frost damage, poison and paralysis, however he does have a slight weakness to fire damage. Once he begins to take damage, he summons three Ice Wraiths to aid him in battle, if given the chance. He also regenerates health very quickly. During the entire battle the ground will shake violently, much like when staggered.

Karstaag isn't that difficult to beat anyway, just take a steel dagger, and don't get caugh by him, then backstab.
You maybe know what a furtive backstab is x30 superior than a regular hit of a battle axe
