The Draugr Deathlord has the innate ability to shout and has learned three shouts:

1/day: Frost Breath. Breathes frigid air in a 30-foot cone. All creatures in that area must make a Constitution saving throw (DC 13). A creature takes 6d8 cold damage on a failed save, or half as much damage on a successful one. A creature killed by this shout becomes a frozen statue until it thaws. Ice forms on any liquid surface within the area of this shout. Each creature that fails the saving throw while standing on the ground is also restrained as its legs are encased in ice, binding them to the ground. A restrained creature can use its action to make a Strength check (DC 13). On a success, it frees itself.

2/day: Disarm. Forces one creature of its choice within 10 feet of it to make a Strength saving throw (DC 13), dropping one item it is holding on a failed save. The item, such as a weapon or a shield, falls to the ground in a random place within 20 feet of the target.

3/day: Unrelenting Force. Uses the power of its voice to stagger all creatures in a 15-foot cone originating from it. Those creatures must succeed on a Strength saving throw (DC 13) or take 2d8 thunder damage and be pushed 10 feet away from it. A creature that succeeds on the save takes half as much damage and isn’t pushed. Creatures failing the saving throw take an additional 1d8 thunder damage and are knocked prone in addition to being pushed.

Undead Fortitude. If damage reduces the draugr to 0 hit points, it must make a Constitution saving throw with a DC of 5+the damage taken, unless the damage is radiant or from a critical hit. On a success, the draugr drops to 1 hit point instead.
