Fallout 4 Deathclaw

Deathclaws are creatures found in the Commonwealth, on the Island and in Nuka-World.

Gameplay
Deathclaws have sharp claws and primarily use them as a melee attack and can throw objects. They may slam the player character into the ground or stagger them. If one of their legs becomes crippled, a broken bone can be seen sticking out of the skin, and they will move slowly. With both legs crippled they are unable to move at all. It is possible to shoot off the end of their tail. If they cannot find a path to their opponent, they will flee and hide behind cover until their target is reachable again.

Variants
The variants that can be encountered are based on the player character's level. Scripted encounters, such as on top of Haymarket Mall and at Lynn Woods, have a higher chance of spawning a next-stage deathclaw than randomly-encountered wasteland ones.

Commonwealth

 * A scripted deathclaw encounter in Concord during the When Freedom Calls quest, after defeating Gristle. Sometimes a bug will occur, causing this deathclaw to be stuck in the ground.
 * Appear in random encounters, including attacks on any owned settlement.
 * A leveled deathclaw is scripted to appear at Garden terrace on the roof of Haymarket Mall. Sometimes a bug will occur, preventing the deathclaw from jumping onto the terrace, so it will remain hanging onto the side of the mall, or permanently passive until the player character attacks it. At higher levels, two deathclaws may appear.
 * Two random encounters can be triggered by throwing the switch on top of the tower in Lynn Woods. This can be repeated every few days once the area has respawned.
 * One can be found guarding the entrance to Old Gullet sinkhole. It is passive until it detects the player character when they first encounter it. Once killed, respawns will often be permanently passive until attacked.
 * A scripted deathclaw can be encountered in the Museum of Witchcraft during the quest The Devil's Due.
 * A scripted deathclaw can be found in a tunnel off the gym area in the Boston Mayoral Shelter.
 * A scripted deathclaw can be encountered at the bottom level of the Kendall Hospital.
 * Two deathclaws can be found west of Natick Banks, by a few satellite dishes, fighting a behemoth. A leveled deathclaw can be found lurking around an abandoned garage with a tanker on the side of the building, a normal deathclaw can be found on the farm just up the road from the matriarch, and one or two leveled deathclaws may be found around the church, fighting a group of leveled super mutants (depending on if the mutants were killed, before the player character's arrival).
 * One can be found in the Robotics Pioneer Park, inside the first house from the fast travel point. Like the Gullet Sinkhole deathclaw, there is a chance that consequent respawns will be passive towards the player character until attacked.
 * On occasion a leveled deathclaw may spawn on the rocks before entering the Edge of the Glowing Sea.
 * One can be found east of The Slog near a bus on the overhead road. It can be seen from the snack bar when looking towards the road to the east on the bus. It will come down and through the water towards the player character if they shoot at it.
 * One can be found in a rock formation close to Coastal cottage, wandering around a couple of Yao Guai corpses.
 * It is possible that one or more deathclaws may spawn on the beach next to Kingsport Lighthouse.

Glowing Sea

 * Two found around the northernmost cave, one near the ruins of a Red Rocket building, the other asleep above the cave, near a broken part of the highway.
 * One found around the southern cave.
 * On the top of a hill south of the capsized factory.
 * Outside the rocky cave, asleep.
 * In the lower level of the parking garage.
 * Near the forgotten church.

Add-ons

 * A lone deathclaw can be encountered on the Island, east of the ruined church. A rocky outcropping nearby has two deathclaw nests, often with deathclaw eggs. May sometimes be passive instead of hostile.
 * One can be found behind a limestone wall in the dig site of Vault 88.
 * Two deathclaws may be found at the bus stop, west-southwest of the Galactic Zone in Nuka-World. One will be patrolling the area, while the second will spawn when the Sole Survivor enters the middle of the area. The second deathclaw will be a higher level spawn.

Appearances
Deathclaws appear in Fallout 4 and its add-ons Far Harbor and Nuka-World.
